Cisco IOS Release 11.3(3a)WA4(6) Release Notes for LightStream 1010 ATM Switch Software

This document describes the features and caveats for Cisco IOS Release 11.3(3a)WA4(6) for the LightStream 1010 ATM switch software. This software is based on Cisco IOS Release 11.3(3a).

Introduction

This document includes the following sections:

Managing the LightStream 1010 ATM Switch from a Remote Subnet

This section applies to Cisco IOS Release 11.3(0.8)TWA4(2) and later releases. If you are managing the LightStream 1010 ATM switch through an Ethernet interface or ATM subinterface on the ATM switch processor (ASP), and your management station or Trivial File Transport Protocol (TFTP) server is on a different subnet than the switch, you must configure a static IP route. lists the steps needed to configure a static IP route.

Caution If you fail to configure a static IP route before installing the new image, you might lose remote administrative access to the switch. If this happens, you can regain access from a direct console connection to the switch, although this requires physical access to the console port on the ASP.


Step	Command	Task
1	enable	Enter privileged EXEC mode.
2	configure terminal	Enter global configuration mode.
3	ip route prefix mask [ethernet \| atm] 2/0/0[.subinterface]	Configure a static IP route on the Ethernet interface or ATM subinterface of the ASP.
4	end	Return to privileged EXEC mode.
5	copy running-config startup-config	Save the configuration to NVRAM.

Syntax Description

prefix---The IP route prefix of the remote network where the management station or TFTP server resides.
mask---The subnet mask of the remote network where the management station or TFTP server resides.
subinterface---The ATM subinterface number on the ASP.

For more information about the ip route command, refer to the LightStream 1010 ATM Switch Command Reference publication.

Software and Associated Hardware

This section describes the software and associated hardware support for the LightStream1010 Multiservice ATM switch.

The software is based on Cisco IOS Release 11.1. This software base is superseded with the WAS3 and WAS4 releases.

Note The WAS1 and WAS2 releases are available on CCO for download.

Permanent virtual path (PVP) tunnel virtual path connection identifier (VPCI) configuration using the atm signalling vpci vpci_number command.
Changed atm ilmi-keepalive [seconds [retry retry]] command to add retry option.
Added new atm signalling ie aal5 mode {stream | message} command to allow statically configured mode field in AAL5 IE on UNI3.0 side connections.
The LightStream 1010 ATM switch supports configuration of multiple switch ATM addresses using the global atm address configuration command. Previously, only the active switch ATM address was used to generate interface related soft PVC addresses. This release of the software to allows soft PVC addresses to be generated based on all switch addresses, instead of only the active switch ATM address. It allows you to change the ATM address of the switch and the soft PVC configuration based on old address continues to be valid, allowing you to modify the soft PVC configuration later to migrate to the new address.

See the "Documentation" section for a list of documents that describe these features.

Cisco IOS Release 11.3(0.8)TWA4(2) Features

The following features have been added to the LightStream 1010 ATM switch software Cisco IOS Release 11.2(0.8)TWA4(2):

PNNI hierarchy

Note

ATM tag switch router (TSR)
E.164 autoconversion
Multipoint-to-point UNI signaling
Substituting other service categories in shaped CBR VP tunnels

See the "Documentation" section for a list of documents that describe these features.

Cisco IOS Release 11.2(8.0.1)FWA4(1) Features

The following features have been added to the LightStream 1010 ATM switch software 11.2(8.0.1)FWA4(1):

Support for feature card per-flow queueing (FC-PFQ), which is a daughtercard on the ATM switch processor (ASP) card. FC-PFQ provides the following new features:
- Per-virtual circuit (VC) or per-virtual path (VP) output queueing
- Rate scheduling (RS) and weighted round robin (WRR) output scheduling
- Multiple, weighted, dynamic thresholds for selective packet marking and discard
- Per-VC or per-VP traffic shaping for constant bit rate (CBR) traffic
- Dual leaky bucket policing

- Network clocking enhancements for smooth switchover
- Per-connection or per-interface nondisruptive snooping
- Shaped VP tunnels for CBR traffic
Closed User Groups (CUGs), which allow users to form logical groups within virtual private networks to restrict access.
Access lists on Integrated Local Management Interface (ILMI) registration, which deny incorrect ATM addresses from being registered through ILMI and advertised on a Private Network-Network Interface (PNNI).
ATM soft restart, which allows you to change some interface parameters without shutting down the interface.
ATM accounting enhancements, including the following new features:
- Accounting enable and disable on individual interfaces
- Shutdown and no shutdown on interfaces on which accounting is enabled
- Periodic data collection
- Support for permanent virtual circuit (PVC) and permanent virtual path (PVP) connection types (two new Management Information Base [MIB] objects: tx_peak_cells and rx_peak_cells [for PVCs or PVPs only])
Signaling diagnostics feature and MIB
Supplemental AToM MIB
Token Ring LANE services

See the "Documentation" section for a list of documents that describe these features.

Memory Requirements

DRAM memory configurations are available in two sizes:

32-MB DRAM (MEM-ASP32M)---This is the default for the LightStream 1010 product.
64-MB DRAM (MEM-ASP64M)---This is optional memory for the LightStream 1010 product.

The amount of DRAM required for the LightStream 1010 is determined by the number of active physical and logical ports (VP tunnels) and the number of active SVCs through the switch.

Table 6 illustrates the DRAM requirements for the LightStream 1010 ATM switch.

Cisco IOS Release 11.3(3a)WA4(6) Caveats Corrected

This section describes caveats from Cisco IOS Release 11.3(2) TWA4(4) that have been corrected by Cisco IOS Release 11.3(3a) WA4(6) of the LightStream 1010 ATM switch software.

CSCdi72255

: Symptom: E3 port adapters are limited to 65535 cells per second per PVC regardless of the framing type. There is no benefit from G832 framing.

CSCdj28496

: Symptom: The fail over time for the circuit emulation switch (CES) soft VC on a redundant link might be inconsistent, from less than 1 second up to 15 seconds.

CSCdj85627

: Symptom: A CES PVC cannot be cross connected to a VP tunnel interface.

CSCdj87463

: Symptom: The CBR interface on the CES port adapter is always in the up/up state, even when no cable is attached, unless it is administratively shut down. If the CBR line goes down, the interface stays up/up, and the only error reported is a Linestate: LossOfSignal.

CSCdj89223

: Symptom: PNNI support of left-justified E.164 AESA addresses is not available in Cisco IOS Release 11.3 (0.8)TWA4(2) release.

CSCdk08318

Symptom: Some LANE clients cannot join an ELAN.

show lane indicates that some LANE clients (still in init state as far as the LANE client router is concerned) appear in the LECS table with no information.
sh atm vc int a13/0/0 indicates that some SVCs are not connected.

If the LANE clients try to join the ELAN, they are rejected.

CSCdk17127

: Symptom: Using more than 13 time slots with cas on-hook, the voice CBR connections were unstable. Without on-hook-detect configuration, all CBR VCs are stable.

CSCdk17133

: Symptom: A ring-back tone cannot be heard from the other side of a PBX when on-hook-detect is set.

CSCdk21557

: Symptom: You cannot use SNMP to create a soft PVC on the ATM switch.

CSCdk29039

: Symptom: The ATM switch might crash if you remove a snooped subinterface by entering the no interface command and then entering the show atm snoop-vc command on the snoop interface.

Cisco IOS Release 11.3(3a)WA4(6) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch for Cisco IOS Release 11.3(3a)WA4(6).

The following caveats have been identified for this release of the LightStream 1010 ATM switch software:

The maximum number of ELAN LES/BUS pairs that the ASP ATM interface supports is 10.
CSCdi55937

: Symptom: Remote defect identification (RDI) cells sent by an end point in response to alarm indication signal (AIS) cells generated at an intermediate switch with a fault condition on an interface are not propagated beyond the intermediate switch. The intermediate switch removes the connection leg entries for both interfaces participating in the connection when a fault is discovered on one of the interfaces, even though the other interface might still be up. As a result, the RDI cells are dropped at the intermediate switch.
: Workaround: None.

CSCdi74229

: Symptom: When more than 1000 SVCs are active on an interface and the shutdown command is entered, all SVCs on that interface are released and the following message appears:

%SYS-3-CPUHOG

: This message indicates that the release process runs for a long time before returning control to the kernel, which can then schedule other tasks. This process does not affect normal operation of the switch.
: Workaround: None.

CSCdi75584

: Symptom: Under very heavy traffic conditions the switch might experience temporary queue cell failures. This should clear after the traffic congestion clears.
: Workaround: None.

CSCdi82954

: Symptom: The receiver circuitry on DS3 port adapters can interpret noise as a valid signal. This signal is framed incorrectly and does not contain real data. The DS3 controller interprets the signal as a bad signal instead of no signal, and the red RX light emitting diode (LED) lights up.
: Workaround: None.

CSCdi83275

: Symptom: When a large number of LANE clients come up and down constantly over extended periods of time, the system can run out of AAL5 buffers and the following message appears:

%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts

: In most cases, the system continues to function normally, but occasionally the system denies additional calls from end systems.
: Workaround: Toggle the interface to reinitialize all connections and restore normal operation.

CSCdi83567

: Symptom: When an AddParty message is sent across an E.164 interface, and the message does not include the CallingPartyAddress information element, the AddParty request is rejected on the first attempt. The second attempt is successful.
: Workaround: Include the CallingPartyAddress information element in the AddParty message.

CSCdi92142

: Symptom: A LECS, using Cisco IOS Version 11.2(X), expects all LESs to establish an individual control VC to the LECS in order to validate clients.
: If different Emulated Local Area Networks (ELANs), using Cisco IOS Release 11.1(X), are configured on multiple subinterfaces of the same physical interface, then all LES(s) multiplex the control messages (which validate the clients) into a single VC.
: For example, see the following LES router configuration:

atm1/0.1    sysa_70k_31_a1.1_LAN sysa_70k_31_a1.1_LAN
atm1/0.2    sysa_70k_31_a1.2_LAN sysa_70k_31_a1.2_LAN
atm1/0.3    sysa_70k_31_a1.3_LAN sysa_70k_31_a1.3_LAN
atm1/0.4    sysa_70k_31_a1.4_LAN sysa_70k_31_a1.4_LAN

: This configuration of an LECS sends the following warning messages to the console stating that an LES of one ELAN is attempting to obtain information about another ELAN:

%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.1_LAN'
%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.2_LAN'
%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.3_LAN'

: The clients are still allowed to join the ELAN. Disregard the warning message.
: Workaround: None.

CSCdj01016

Symptom: You can create variable bit rate (VBR), available bit rate (ABR), and unspecified bit rate (UBR) VCs across the switch with peak cell rate (PCR) values greater than the interface line rate. However, the actual allocated bandwidth continues to be:

VBR: sustained cell rate (SCR) + sustained-cell-rate-margin-factor x (PCR - SCR).
ABR, UBR: no bandwidth is allocated.

Workaround: None.

CSCdj01757

: Symptom: When one of the installed power supplies is powered OFF, and you are copying an image to bootflash, a power supply failure message appears.
: Workaround: None.

CSCdj10889

: Symptom: The call attempt counters for PortSelectGroups might not count the outgoing calls on its NNI interfaces because of switch crankback attempts. This might result in a discrepancy between the call attempt counters shown on Portselgroup representing the interface on which the call came in and the counters shown on the PortSelgroup representing the interface over which an attempt was made to forward the call. This problem might occur when a call fails.
: Workaround: None.

CSCdj11070

: Symptom: If you disable Cisco Discovery Protocol (CDP) on the 2/0/0.x interface and it is configured as a LEC, the information is not saved to NVRAM when you enter the copy running-config startup-config command. CDP is disabled in the running configuration, but it is reenabled after a system reload.
: Workaround: None.

CSCdj13565

: Symptom: ATM RMON data collection is not supported on subinterfaces or tunnels. The atm rmon collect command is accepted on hardware interfaces only; it is ignored on subinterfaces. SNMP and NVGEN support (via portSelTable) is not possible until the Interfaces MIB (RFC 1573) entries are added for tunnel subinterfaces. ATM RMON counters for a hardware interface do not include any of the traffic through tunnels configured on the interface.
: Workaround: None.

CSCdj18430

: Symptom: The cell count reported on a snooped interface is twice the actual number of cells transmitted.
: Workaround: None.

CSCdj18583

: Symptom: Supporting ABR VP tunnels require interaction between VP flow-control and VC marking that neither FC-PCQ nor FC-PFQ hardware can perform. The configuration of an ABR VP tunnel subinterface is prevented.
: Workaround: None.

CSCdj18678

: Symptom: SNMP support of the ciscoAtmIfPhysEntryData table and LED information is not available on the 25-MB port adapter.
: Workaround: None.

CSCdj24272

: Symptom: The system crashes when you enter the no shutdown command on an E3 interface and the port adapter is not installed.
: Workaround: None.

CSCdj25772

: Symptom: Cell loss might occur while hot swapping a power supply.
: Workaround: None.

CSCdj32484

: Symptom: A TFTP download to a LightStream 1010 ATM switch might fail because of an ARP table corruption problem.
: Workaround: Enter the ip host-routing command before attempting a TFTP download.

CSCdj42669

: Symptom: Spurious memory messages display when trying to create 96 tunnels between two ATM switches on three links.
: Workaround: None.

CSCdj42967

: Symptom: When memory is almost or completely exhausted and a soft PVC goes down, it might not come back up, leaving it in a releasing or inactive state.
: Workaround: None.

CSCdj54954

: Symptom: In an LightStream 1010 ATM switch equipped with an FC-PFQ, the maximum number of cells available for use is 64511. The number of cells in the switch fabric is 65535.
: Workaround: None.

CSCdj59621

: Symptom: The system does not support CUGs on soft PVC connections. For example, if you define a set of access policies and a CUG on an interface with the PVC leg of a soft PVC call, the CUG parameters do not apply to those calls.
: Workaround: None.

CSCdj59640

: Symptom: When running a test between two CES ports, you might see AIS problems when a CES DSX1 loopback payload is activated.
: Workaround: None.

CSCdj68412:

: Symptom: If there are multiple parallel paths to the same destination on a LightStream 1010 with a FC-PFQ feature card installed, the tag switching VCs (TVCs) should be load balanced on a per network prefix basis over these parallel paths (up to a maximum of 4 parallel paths) instead of being VC merged. Load balancing does not happen in some cases and the TVCs might be VC merge and go out of the switch as a single VC.
: Workaround: None.

CSCdj71109

: Symptom: The ATM switch does not currently support maxvc-number negotiation through ILMI.
: Workaround: None.

CSCdj71876

: Symptom: Under some rare conditions (not yet identified), some ports might get stuck in the WaitDevType state.
: Workaround: Reboot the switch.

CSCdj72651

: Symptom: Shutting down an interface with more than 1000 tag switching VCs may cause a CPUHOG occurrence for the EXEC process.
: Workaround: There is no Workaround for this problem. The CPUHOG occurrence does not impact the functionality of the ATM switch.

CSCdj78305

: Symptom: IP host-routing does not disable when specified.
: Workaround: Enable and disable ip routing and then save the configuration to NVRAM.

CSCdj82930

: Symptom: Open shortest path first (OSPF) does not recognize more than four parallel interfaces. This might cause some tag VCs (TVCs) to not get switched to other interfaces if a tunnel carrying the TVCs is shut down.
: Workaround: Enter a clear ip route command on the switch on the interface that was shut, or a clear ip route command on all the switches to bring everything back up most of the time. If the clear ip route command does not work, enter a shut/no shut command on the UNI interfaces on the switch on which the physical interface was shut to bring everything back up.

CSCdj84344

: Symptom: There is a small divergence in the measured output of the shaped VP tunnels at rates of 90 Mbps and above.
: Workaround: None.

CSCdj84379

: Symptom: The granularity provided by the FC-PFQ feature card scheduling hardware does not allow an exact match of all requested cell rates. To satisfy the traffic contract guarantee, the next higher available scheduling value is used. A shaped VP tunnel is used frequently to pass data to a WAN VP trunk, and limits the traffic transmitted to the scheduled rate. This can cause cells to be dropped in the WAN. Any dropping must be done prior to multiplexing onto the VP, so that a packet discard can be performed.
: Workaround: Refer to the information in the DDTs for information on how to make a conversion of a requested rate to the actual rate.

CSCdj85853

: Symptom: When you set the ROM monitor environment variable boot to a nonexistent file (using the Cisco IOS command boot system flash) and the configuration register is set to 0x2102 (autoboot), the switch hangs during the subsequent reload command issued by the software.
: Workaround: Power-cycle the switch; a break character is sent to the switch to force it to the ROM monitor prompt. You can then manually reboot the switch.

CSCdj86073

: Symptom: The following messages might appear on the LightStream 1010 switch console:
: SYS-3-MGDTIMER Unitialized timer
: This message is harmless and no loss of function occurs.
: Workaround: None.

CSCdk01031

Symptom: Using the atm ping command without specifying VCI value uses last VCI value automatically.

When using the atm ping command with OAM cells, and you only specify a VPI (but no VCI), the software takes one of these VCI values:

Last VCI used if an ATM ping was executed
Lowest VCI value if no prior ATM pings were executed

CSCdk06610

: Symptom: A LightStream 1010 switch installed in the Catalyst 5500 chassis might fail to boot up when using mixed power supplies at high temperatures.
: When using power supplies from different vendors on the Catalyst 5500 chassis, make sure that the supplies are powered-up in serial order. If you power-up the power supplies simultaneously, the ASP on the LightStream 1010 ATM switch might not come out of reset. For example, the ASP might hang and not boot.

CSCdk07378

: Symptom: Funnel VCs can jeopardize quality of service (QoS) for services.
: The current multipoint-to-point funnel implementation can compromise the QOS guarantees of other connections (guaranteed services) when the application that created the funnel SVC malfunctions. For example, if the application were to transmit traffic on more than one leg of the funnel SVC simultaneously, the rate scheduler on the output interface will over-subscribe and, potentially, affect the peak cell rate (PCR), sustained cell rate (SCR), and maximum cell rate (MCR) guarantees for other VCs on the interface.

CSCdk10398

: Symptom: ILMI does not come up upon reload of vp-mux (vuni).
: ILMI on the tunnel interface (connected to the far-end peer device through a vp-mux switch and virtual UNI) has trouble staying in "WaitDevType" after reload of the vp-mux switch.
: Workarond: This situation can be cleared by shutting down the tunnel interface; disabling the ILMI followed by the no shut command on the tunnel interface. After the interface settles down, the ILMI on the tunnel can be re-enabled. Shut the interface. Use the commands atm ilmi-enable and atm auto-configuration (if desired), then re-enable the tunnel interface with the no shut command.

Cisco IOS Release 11.3(2a)WA4(4) Caveats Corrected

This section describes caveats from Cisco IOS Release 11.3(0.8) TWA4(2) that have been corrected by Cisco IOS Release 11.3(2) TWA4(4) of the LightStream 1010 ATM switch software.

CSCdk01707

: Symptom: When a write bus error occurs, the system memory could be corrupted.

CSCdk04816

: The LightStream 1010 switch supports configuration of multiple switch addresses using the global atm address configuration command. Previously, only the active switch address was used to generate interface related soft PVC addresses. In this release the soft PVC addresses are generated based on all switch addresses, instead of just the active switch address. If you change the switch address, the soft PVC configuration based on old address continues to be valid, allowing you to modify soft PVC configuration later to migrate to the new address.

CSCdk01629

: Symptom: Some vendor switches running LANE 3.0 reject UNI 3.1 connections because of the absence of the ATM signaling AAL5 IE mode field.
: In the LANE 3.0 specification, the mode field is mandatory in the AAL5 IE. In the UNI 3.1 specification, the mode field was removed. When the setup originates from the UNI3.1 side, it does not have the mode field. For interoperability, the new CLI atm signalling ie aal5 mode command has been added to allow you to configure a mode field statically to be carried in AAL5 IE while running UNI 3.0. By default, this command is on. On a UNI 3.0 connection side a message mode will be passed if a setup is received from a UNI 3.1 side connection. You can change the ATM signalling AAL5 IE mode from message to stream, or disable the command.

CSCdj25769

: Symptom: An OC12 port adapter on a LightStream 1010 ATM switch, which was configured as a network clock source, results in bad clock quality.

CSCdj90806

: Symptom: When the soft VC connected over a VP tunnel route is broken, it takes approximately 45 seconds to reestablish the soft VC over an alternative path, because the destination end of the soft VC is not released soon enough. Shortening the time it takes ILMI to detect the keepalive failure can speed the process to release the destination end of the soft VC and reestablish an alternative route.
: In Cisco IOS Release 11.3 (0.8)TWA4(2), ILMI would retry the keepalive polling five times (a fixed number) before declaring the link down. You can configure the keep-alive timer between 1 to 429,4967 seconds (default is 5 seconds).
: To solve this problem, Cisco IOS Release 11.3(2a)WA4(4) has an additional keyword, retry, in the atm ilmi-keepalive command, and the timer accuracy has been improved.
: The new command changes are as follows:
: atm ilmi-keepalive [seconds [retry retry]]

CSCdj91890

: Symptom: If you deleted and recreated the PNNI lowest-level nodes simultaneously on multiple nodes in the same network using the no node node_number lowest command in the config-atm-router mode, you might cause one of these nodes to crash.

CSCdj94322

: Symptom: The input queue on interface atm 2/0/0 of the LightStream 1010 switch, configured as a Token Ring LANE client, might fill up with 34-byte packets. The packets originate from a Cisco 4700 router LEC, and are destined to the LEC of the LightStream 1010 switch.

CSCdj74422

: Symptom: When a LightStream 1010 switch running Cisco IOS Release 11.3 is connected to another running Cisco IOS Release 11.2, and it tries to allocate VCI to equal 32 (VCI=32), the switch running 11.3 does not accept the value because the VCI values 32, 33, and 34 are reserved in Cisco IOS Release 11.3 and later.
: In this case the call will not succeed for the first three attempts, and will only succeed once the vpi/vci assignments increment to 35. There are no operational problems with this caveat.

CSCdj88091

: Symptom: An ATM-signaling SETUP message does not automatically negotiate-down the PCR to the minimum line rate through which the SETUP passes.
: This occurs if the SETUP enters the switch via a network to network interface (NNI). If the SETUP enters the switch via a UNI 4.0 interface, the PCR to the minimum line rate negotiation is performed.

CSCdk02119

: Symptom: PNNI port numbers for internal prefixes are updated incorrectly in the routing table when the received prefixes advertise non-zero port numbers. This problem occurs only with internal prefixes and not with exterior routes. This is only important when the routes have to be flushed and are not removed from the routing table; you can see these routes using the show atm route command. However, these entries do get removed from the PNNI database, and the routes are marked as "DN" in the routing table; you can see the stale entries using the show atm route command. This problem does not occur in an all Cisco environments.

Cisco IOS Release 11.3(2a)WA4(4) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch for Cisco IOS Release 11.3(2a)WA4(4).

The following caveats have been identified for this release of the LightStream 1010 ATM switch software:

CSCdj42669

: Symptom: Spurious memory messages display when trying to create 96 tunnels between two ATM switches on three links.
: Workaround: None.

CSCdj72651

: Symptom: Shutting down an interface with more than 1000 tag switching VCs may cause a CPUHOG occurrence for the EXEC process.
: Workaround: There is no Workaround for this problem. The CPUHOG occurrence does not impact the functionality of the ATM switch.

CSCdj68412

: Symptom: If there are multiple parallel paths to the same destination on a LightStream 1010 with a FC-PFQ feature card installed, the tag switching VCs (TVCs) should be load balanced on a per network prefix basis over these parallel paths (up to a maximum of 4 parallel paths) instead of being VC merged. Load balancing does not happen in some cases and the TVCs might be VC merge and go out of the switch as a single VC.
: Workaround: None.

CSCdk01031

Symptom: Using the atm ping command without specifying VCI value uses last VCI value automatically.

When using the atm ping command with OAM cells, and you only specify a VPI (but no VCI), the software takes one of these VCI values:

Last VCI used if an ATM ping was executed
Lowest VCI value if no prior ATM pings were executed

CSCdk06610

: Symptom: A LightStream 1010 switch installed in the Catalyst 5500 chassis might fail to boot up when using mixed power supplies at high temperatures.
: When using power supplies from different vendors on the Catalyst 5500 chassis, make sure that the supplies are powered-up in serial order. If you power-up the power supplies simultaneously, the ASP on the LightStream 1010 ATM switch might not come out of reset. For example, the ASP might hang and not boot.

CSCdk07378

: Symptom: Funnel VCs can jeopardize quality of service (QoS) for services.
: The current multipoint-to-point funnel implementation can compromise the QOS guarantees of other connections (guaranteed services) when the application that created the funnel SVC malfunctions. For example, if the application were to transmit traffic on more than one leg of the funnel SVC simultaneously, the rate scheduler on the output interface will over-subscribe and, potentially, affect the peak cell rate (PCR), sustained cell rate (SCR), and maximum cell rate (MCR) guarantees for other VCs on the interface.

CSCdk08318

: Problem: Occasionally, some lane clients cannot join an ELAN.
: Workaround: None.

CSCdi55937

: Symptom: Remote defect identification (RDI) cells sent by an end point in response to alarm indication signal (AIS) cells generated at an intermediate switch with a fault condition on an interface are not propagated beyond the intermediate switch. The intermediate switch removes the connection leg entries for both interfaces participating in the connection when a fault is discovered on one of the interfaces, even though the other interface might still be up. As a result, the RDI cells are dropped at the intermediate switch.
: Workaround: None.

CSCdi72255

: Symptom: E3 port adapters are limited to 65535 cells per second per PVC regardless of the framing type. There is no benefit from G832 framing.
: Workaround: None.

CSCdi74229

: Symptom: When more than 1000 SVCs are active on an interface and the shutdown command is entered, all SVCs on that interface are released and the following message appears:

%SYS-3-CPUHOG

: This message indicates that the release process runs for a long time before returning control to the kernel, which can then schedule other tasks. This process does not affect normal operation of the switch.
: Workaround: None.

CSCdi75584

: Symptom: Under very heavy traffic conditions the switch might experience temporary queue cell failures. This should clear after the traffic congestion clears.
: Workaround: None.

CSCdi82954

: Symptom: The receiver circuitry on DS3 port adapters can interpret noise as a valid signal. This signal is framed incorrectly and does not contain real data. The DS3 controller interprets the signal as a bad signal instead of no signal, and the red RX light emitting diode (LED) lights up.
: Workaround: None.

CSCdi83275

: Symptom: When a large number of LANE clients come up and down constantly over extended periods of time, the system can run out of AAL5 buffers and the following message appears:

%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts

: In most cases, the system continues to function normally, but occasionally the system denies additional calls from end systems.
: Workaround: Toggle the interface to reinitialize all connections and restore normal operation.

CSCdi83567

: Symptom: When an AddParty message is sent across an E.164 interface, and the message does not include the CallingPartyAddress information element, the AddParty request is rejected on the first attempt. The second attempt is successful.
: Workaround: Include the CallingPartyAddress information element in the AddParty message.

CSCdi92142

: Symptom: A LECS, using Cisco IOS Version 11.2(X), expects all LESs to establish an individual control VC to the LECS in order to validate clients.
: If different Emulated Local Area Networks (ELANs), using Cisco IOS Release 11.1(X), are configured on multiple subinterfaces of the same physical interface, then all LES(s) multiplex the control messages (which validate the clients) into a single VC.
: For example, see the following LES router configuration:

atm1/0.1    sysa_70k_31_a1.1_LAN sysa_70k_31_a1.1_LAN
atm1/0.2    sysa_70k_31_a1.2_LAN sysa_70k_31_a1.2_LAN
atm1/0.3    sysa_70k_31_a1.3_LAN sysa_70k_31_a1.3_LAN
atm1/0.4    sysa_70k_31_a1.4_LAN sysa_70k_31_a1.4_LAN

: This configuration of an LECS sends the following warning messages to the console stating that an LES of one ELAN is attempting to obtain information about another ELAN:

%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.1_LAN'
%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.2_LAN'
%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.3_LAN'

: The clients are still allowed to join the ELAN. Disregard the warning message.
: Workaround: None.

CSCdj01016

VBR: sustained cell rate (SCR) + sustained-cell-rate-margin-factor x (PCR - SCR).
ABR, UBR: no bandwidth is allocated.

Workaround: None.

CSCdj01757

: Symptom: When one of the installed power supplies is powered OFF, and you are copying an image to bootflash, a power supply failure message appears.
: Workaround: None.

CSCdj03229

: Symptom: A DS3 interface connected to a Cisco BPX switch occasionally goes down and back up after you enter the no shutdown command. The interface operates normally after it comes up the second time.
: Workaround: None.

CSCdj10889

: Symptom: The call attempt counters for PortSelectGroups might not count the outgoing calls on its NNI interfaces because of switch crankback attempts. This might result in a discrepancy between the call attempt counters shown on Portselgroup representing the interface on which the call came in and the counters shown on the PortSelgroup representing the interface over which an attempt was made to forward the call. This problem might occur when a call fails.
: Workaround: None.

CSCdj11070

: Symptom: If you disable Cisco Discovery Protocol (CDP) on the 2/0/0.x interface and it is configured as a LEC, the information is not saved to NVRAM when you enter the copy running-config startup-config command. CDP is disabled in the running configuration, but it is reenabled after a system reload.
: Workaround: None.

CSCdj13565

: Symptom: ATM RMON data collection is not supported on subinterfaces or tunnels. The atm rmon collect command is accepted on hardware interfaces only; it is ignored on subinterfaces. SNMP and NVGEN support (via portSelTable) is not possible until the Interfaces MIB (RFC 1573) entries are added for tunnel subinterfaces. ATM RMON counters for a hardware interface do not include any of the traffic through tunnels configured on the interface.
: Workaround: None.

CSCdj18430

: Symptom: The cell count reported on a snooped interface is twice the actual number of cells transmitted.
: Workaround: None.

CSCdj18583

: Symptom: Supporting ABR VP tunnels require interaction between VP flow-control and VC marking that neither FC-PCQ nor FC-PFQ hardware can perform. The configuration of an ABR VP tunnel subinterface is prevented.
: Workaround: None.

CSCdj18678

: Symptom: SNMP support of the ciscoAtmIfPhysEntryData table and LED information is not available on the 25-MB port adapter.
: Workaround: None.

CSCdj24272

: Symptom: The system crashes when you enter the no shutdown command on an E3 interface and the port adapter is not installed.
: Workaround: None.

CSCdj25772

: Symptom: Cell loss might occur while hot swapping a power supply.
: Workaround: None.

CSCdj28496

: Symptom: The fail over time for the circuit emulation switch (CES) soft VC on a redundant link might be inconsistent, from less than 1 second up to 15 seconds.
: Workaround: None.

CSCdj32484

: Symptom: A TFTP download to a LightStream 1010 ATM switch might fail because of an ARP table corruption problem.
: Workaround: Enter the ip host-routing command before attempting a TFTP download.

CSCdj42967

: Symptom: When memory is almost or completely exhausted and a soft PVC goes down, it might not come back up, leaving it in a releasing or inactive state.
: Workaround: None.

CSCdj54954

: Symptom: In an LightStream 1010 ATM switch equipped with an FC-PFQ, the maximum number of cells available for use is 64511. The number of cells in the switch fabric is 65535.
: Workaround: None.

CSCdj59621

: Symptom: The system does not support CUGs on soft PVC connections. For example, if you define a set of access policies and a CUG on an interface with the PVC leg of a soft PVC call, the CUG parameters do not apply to those calls.
: Workaround: None.

CSCdj59640

: Symptom: When running a test between two CES ports, you might see AIS problems when a CES DSX1 loopback payload is activated.
: Workaround: None.

CSCdj71109

: Symptom: The ATM switch does not currently support maxvc-number negotiation through ILMI.
: Workaround: None.

CSCdj71876

: Symptom: Under some rare conditions (not yet identified), some ports might get stuck in the WaitDevType state.
: Workaround: Reboot the switch.

CSCdj78305

: Symptom: When IP host routing is enabled and saved to NVRAM, the only way you can remove this command from the configuration is to enable and disable IP routing in Cisco IOS Release 11.3 (0.8) TWA4(2).
: Workaround: None.

CSCdj82930

: Symptom: Open shortest path first (OSPF) does not recognize more than four parallel interfaces. This might cause some tag VCs (TVCs) to not get switched to other interfaces if a tunnel carrying the TVCs is shut down.
: Workaround: Enter a clear ip route command on the switch on the interface that was shut, or a clear ip route command on all the switches to bring everything back up most of the time. If the clear ip route command does not work, enter a shut/no shut command on the UNI interfaces on the switch on which the physical interface was shut to bring everything back up.

CSCdj84344

: Symptom: There is a small divergence in the measured output of the shaped VP tunnels at rates of 90 Mbps and above.
: Workaround: None.

CSCdj84379

: Symptom: The granularity provided by the FC-PFQ feature card scheduling hardware does not allow an exact match of all requested cell rates. To satisfy the traffic contract guarantee, the next higher available scheduling value is used. A shaped VP tunnel is used frequently to pass data to a WAN VP trunk, and limits the traffic transmitted to the scheduled rate. This can cause cells to be dropped in the WAN. Any dropping must be done prior to multiplexing onto the VP, so that a packet discard can be performed.
: Workaround: Refer to the information in the DDTs for information on how to make a conversion of a requested rate to the actual rate.

CSCdj85627

: Symptom: A CES PVC cannot be cross connected to a VP tunnel interface.
: Workaround: Use CES soft-VCs instead; a soft CES VC will connect to a tunnel interface.

CSCdj85853

: Symptom: When you set the ROM monitor environment variable boot to a nonexistent file (using the Cisco IOS command boot system flash) and the configuration register is set to 0x2102 (autoboot), the switch hangs during the subsequent reload command issued by the software.
: Workaround: Power-cycle the switch; a break character is sent to the switch to force it to the ROM monitor prompt. You can then manually reboot the switch.

CSCdj86073

: Symptom: The following messages might appear on the LightStream 1010 switch console:
: SYS-3-MGDTIMER Unitialized timer
: This message is harmless and no loss of function occurs.
: Workaround: None.

CSCdj87463

: Symptom: The CBR interface on the CES port adapter is always in the up/up state, even when no cable is attached, unless it is administratively shut down. If the CBR line goes down, the interface stays up/up, and the only error reported is a Linestate: LossOfSignal.
: Workaround: Administratively shut down the interface.

CSCdj88091

: Symptom: An ATM-signaling SETUP message does not automatically negotiate-down the PCR to the minimum line rate through which the SETUP passes.
: This occurs if the SETUP enters the switch via a NNI interface. If the SETUP enters the switch via a UNI 4.0 interface, the PCR to the minimum line rate negotiation is performed.
: Workaround: None.

CSCdj89223

: Symptom: PNNI support of left-justified E.164 AESA addresses is not available in Cisco IOS Release 11.3 (0.8)TWA4(2) release. This feature will be released at the next maintenance release.
: Workaround: None.

CSCdk08318

: Symptom: Occasionally, some lane clients cannot join an ELAN.
: Workaround: None.

CSCdk17127

: Symptom: Using more than 13 time slots with cas on-hook, the voice CBR connections were unstable. Without on-hook-detect configuration, all CBR VCs are stable.

CSCdk17133

: Symptom: A ring-back tone cannot be heard from the other side of a PBX when on-hook-detect is set.

CSCdk21557

: Symptom: You cannot use SNMP to create a soft PVC on the ATM switch.
: Workaround: None.

CSCdk29039

: Symptom: The ATM switch might crash if you remove a snooped subinterface by entering the no interface command and then entering the show atm snoop-vc command on the snoop interface.
: Workaround: None.

The maximum number of ELAN LES/BUS pairs that the ASP ATM interface supports is 10.

Cisco IOS Release 11.3(0.8)TWA4(2) Caveats Corrected

This section describes caveats from Cisco IOS Release 11.2(8.0.1)FWA4(1) that have been corrected by Cisco IOS Release 11.3(0.8)TWA4(2) of the LightStream 1010 ATM switch software.

CSCdj12108

: Symptom: The bug corrupts the stack and the stack eventually crashes while calling find_buddy repeatedly. A watchdog timeout then causes a reload.

CSCdj42070

: Symptom: Spurious memory access messages appear when you enter the debug atm packet command on one of the interfaces of the LightStream 1010 ATM switch. This caveat was first found in Cisco IOS Release 11.2 (8.0.1) FWA4(1).

CSCdj50627

: Symptom: With multiple LES/BUS pairs configured on a LightStream 1010 ATM switch and about 20 LECs configured to join the ELANs, repeated shutdown or no shutdown of the interface for an extended time could produce the following error message:

ATMS2000_add_party_to_output_only_errors

CSCdj53797

: Symptom: The system sends out excessive ARPs on the Ethernet interface when ip host-routing is enabled.

CSCdj57479

: Symptom: When you configure LES/BUS LANE service on the CPU port, and there is heavy signaling traffic, usually when the switch resets and tries to come back up with a large number of clients for each LES/BUS, the following warning message appears:

CPUHOG - atmsig_output

: This has no impact on the system functionality or performance. This caveat was first found in Cisco IOS Release 11.2 (8.0.1) FWA4(1).

CSCdj56808

: Symptom: When you set multiple VP tunnels between the same neighbor, PNNI does not switch to a better tunnel for flooding when an alternate is possible. Using a VP tunnel that has less tolerance for cell delay variation (CDV) causes cell drops and a failure to complete database synchronization. This caveat was first noticed in Cisco IOS Release 11.2 (8.0.1) FWA4(1).

CSCdj81680

: Symptom: OAM cells with invalid type are passed through the switch rather than being discarded.

CSCdj70489

: Symptom: You can not configure the LightStream 1010 switch for a core-dump using FTP because the FTP subsystem is not included in the LightStream 1010 image. This caveat was first found in Cisco IOS Release 11.2(8.0.1)FWA4(1).

CSCdj84656

: Symptom: Globally disabling ATM accounting did not turn off file_full traps. This caveat was first discovered in Cisco IOS Release 11.2(8.0.1)FWA4(1).

Cisco IOS Release 11.3(0.8)TWA4(2) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch for Cisco IOS Release 11.3TWA4.

The following caveats have been identified for this release of the LightStream 1010 ATM switch software:

CSCdk04816

: The LightStream 1010 switch supports configuration of multiple switch addresses using the global atm address configuration command. Only the active switch addresses are used to generate interface related soft PVC addresses.
: This problem has been resolved in Cisco IOS Release 11.3(2a)WA4(4).
: Workaround: Update the software to Cisco IOS Release 11.3(2a)WA4(4).

CSCdk01629

: Symptom: Some vendor switches running LANE 3.0 reject UNI 3.1 connections because of the absence of the ATM signaling AAL5 IE mode field.
: In the LANE 3.0 specification, the mode field is mandatory in the AAL5 IE. In the UNI 3.1 specification, the mode field was removed. When the setup originates from the UNI 3.1 side, it does not have the mode field. For interoperability, the new CLI atm signalling ie aal5 mode command has been added to Cisco IOS Release 11.3(2a)WA4(4) of the software to allow you to configure a mode field statically to be carried in AAL5 IE while running UNI 3.0. By default, this command is on. On a UNI 3.0 connection side, a message mode will be passed if a setup is received from a UNI 3.1 side connection you can change the ATM signaling AAL5 IE mode from message to stream, or disable the command.
: Workaround: Update the software to Cisco IOS Release 11.3(2a)WA4(4).

CSCdj25769

: Symptom: An OC12 port adapter on a LightStream 1010 ATM switch, which was configured as a network clock source, results in bad clock quality.
: This problem has been resolved in Cisco IOS Release 11.3(2a)WA4(4).
: Workaround: Update the software to Cisco IOS Release 11.3(2a)WA4(4).

CSCdj90806

: Symptom: When the soft VC over a VP tunnel route is broken, it takes approximately 45 seconds to reestablish the soft VC over an alternative path because the destination end of the soft VC is not released soon enough. Shortening the time it takes ILMI to detect the keepalive failure can speed the process to release the destination end of the soft VC and re-establish an alternative route.
: In release11.3(0.8) TWA4(2), ILMI would retry the keepalive polling five times (a fixed number) before declaring the link down. You can configure the keepalive timer between 1 to 429,4967 seconds (default is 5 seconds).
: To solve this problem, Cisco IOS Release 11.3(2a)WA4(4) has an additional keyword, retry, in the atm ilmi-keepalive command, and the timer accuracy has been improved.
: The new command changes are as follows:
: atm ilmi-keepalive [seconds retry]]
: This problem has been resolved in Cisco IOS Releases 11.3(2a)WA4(4) and 11.3(02.03)CI07.
: Workaround: Modify the ATM ILMI keepalive timer to less than 5 seconds, or update the software to Cisco IOS Release 11.3(2a)WA4(4).

CSCdj91890

: Symptom: If you delete and recreate the PNNI lowest-level nodes simultaneously on multiple nodes in the same network using the no node node_number lowest command in config-atm-router mode, you might cause one of these nodes to crash.
: This problem has been resolved in Cisco IOS Release 11.3(2a)WA4(4).
: Workaround: Update the software to Cisco IOS Release 11.3(2a)WA4(4).

CSCdj94322

: Symptom: The input queue on interface atm 2/0/0 of the LightStream 1010 switch, configured as a Token Ring LANE client, might fill up with 34-byte packets. The packets originate from a Cisco 4700 router LEC, and are destined to the LEC of the LightStream 1010 switch.
: This problem has been resolved in Cisco IOS Release 11.3(2a)WA4(4).
: Workaround: Update the software to Cisco IOS Release 11.3(2a)WA4(4).

CSCdi55937

: Symptom: Remote defect identification (RDI) cells sent by an end point in response to alarm indication signal (AIS) cells generated at an intermediate switch with a fault condition on an interface are not propagated beyond the intermediate switch. The intermediate switch removes the connection leg entries for both interfaces participating in the connection when a fault is discovered on one of the interfaces, even though the other interface might still be up. As a result, the RDI cells are dropped at the intermediate switch.
: Workaround: None.

CSCdi72255

: Symptom: E3 port adapters are limited to 65535 cells per second per PVC regardless of the framing type. There is no benefit from G832 framing.
: Workaround: None.

CSCdi74229

: Symptom: When more than 1,000 SVCs are active on an interface and the shutdown command is entered, all SVCs on that interface are released and the following message appears:

%SYS-3-CPUHOG

: This message indicates that the release process runs for a long time before returning control to the kernel, which can then schedule other tasks. This process does not affect normal operation of the switch.
: Workaround: None.

CSCdi75584

: Symptom: Under very heavy traffic conditions, the switch might experience temporary queue cell failures. This should clear after the traffic congestion clears.
: Workaround: None.

CSCdi82954

: Symptom: The receiver circuitry on DS3 port adapters can interpret noise as a valid signal. This signal is framed incorrectly and does not contain real data. The DS3 controller interprets the signal as a bad signal instead of no signal, and the red RX light emitting diode (LED) lights up.
: Workaround: None.

CSCdi83275

: Symptom: When a large number of LANE clients come up and down constantly over extended periods of time, the system can run out of AAL5 buffers and the following message appears:

%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts

: In most cases, the system continues to function normally, but occasionally the system denies additional calls from end systems.
: Workaround: Toggle the interface to reinitialize all connections and restore normal operation.

CSCdi83567

: Symptom: When an AddParty message is sent across an E.164 interface, and the message does not include the CallingPartyAddress information element, the AddParty request is rejected on the first attempt. The second attempt is successful.
: Workaround: Include the CallingPartyAddress information element in the AddParty message.

CSCdi92142

: Symptom: A LECS, using Cisco IOS Release 11.2(X), expects all LESs to establish an individual control VC to the LECS in order to validate clients.
: If you configure different Emulated Local Area Networks (ELANs), using Cisco IOS Release 11.1(X), on multiple subinterfaces of the same physical interface, then all LES(s) multiplex the control messages (which validate the clients) into a single VC.
: For example, see the following LES router configuration:

atm1/0.1    sysa_70k_31_a1.1_LAN sysa_70k_31_a1.1_LAN
atm1/0.2    sysa_70k_31_a1.2_LAN sysa_70k_31_a1.2_LAN
atm1/0.3    sysa_70k_31_a1.3_LAN sysa_70k_31_a1.3_LAN
atm1/0.4    sysa_70k_31_a1.4_LAN sysa_70k_31_a1.4_LAN

: This configuration of an LECS sends the following warning messages to the console stating that an LES of one ELAN is attempting to obtain information about another ELAN:

%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.1_LAN'

'sysa_70k_31_a1.3_LAN'

: The clients are still allowed to join the ELAN. Disregard the warning message.
: Workaround: None.

CSCdj01016

VBR: sustained cell rate (SCR) + sustained-cell-rate-margin-factor x (PCR - SCR).
ABR, UBR: no bandwidth is allocated.

Workaround: None.

CSCdj01757

: Symptom: When one of the installed power supplies is powered OFF, and you are copying an image to bootflash, a power supply failure message appears.
: Workaround: None.

CSCdj03229

: Symptom: A DS3 interface connected to a Cisco BPX switch occasionally goes down and back up after you enter the no shutdown command. The interface operates normally after it comes up the second time.
: Workaround: None.

CSCdj10889

: Symptom: The call attempt counters for PortSelectGroups might not count the outgoing calls on its NNI interfaces because of switch crankback attempts. This might result in a discrepancy between the call attempt counters shown on Portselgroup representing the interface on which the call came in and the counters shown on the PortSelgroup representing the interface over which an attempt was made to forward the call. This problem might be occur when a call fails.
: Workaround: None.

CSCdj11070

: Symptom: If you disable Cisco Discovery Protocol (CDP) on the 2/0/0.x interface and it is configured as a LEC, the information is not saved to NVRAM when you enter the copy running-config startup-config command. CDP is disabled in the running configuration, but it reenabled after a system reload.
: Workaround: None.

CSCdj13565

: Symptom: ATM RMON data collection is not supported on subinterfaces or tunnels. The atm rmon collect command is accepted on hardware interfaces only; it is ignored on subinterfaces. SNMP and NVGEN support (via portSelTable) is not possible until the interfaces MIB (RFC 1573) entries are added for tunnel subinterfaces. ATM RMON counters for a hardware interface do not include any of the traffic through tunnels configured on the interface.
: Workaround: None.

CSCdj18430

: Symptom: The cell count reported on a snooped interface is twice the actual number of cells transmitted.
: Workaround: None.

CSCdj18583

: Symptom: Supporting ABR VP tunnels require interaction between VP flow-control and VC marking that neither FC-PCQ nor FC-PFQ hardware can perform. The configuration of an ABR VP tunnel subinterface is prevented.
: Workaround: None.

CSCdj18678

: Symptom: SNMP support of the ciscoAtmIfPhysEntryData table and LED information is not available on the 25-MB port adapter.
: Workaround: None.

CSCdj24272

: Symptom: The system crashes when you enter the no shutdown command on an E3 interface and the port adapter is not installed.
: Workaround: None.

CSCdj25772

: Symptom: Cell loss might occur while hot swapping a power supply.
: Workaround: None.

CSCdj28496

: Symptom: The failover time for the circuit emulation switch (CES) soft VC on a redundant link might be inconsistent, from less than 1 second up to 15 seconds.
: Workaround: None.

CSCdj32484

: Symptom: A TFTP download to a LightStream 1010 ATM switch might fail because of an ARP table corruption problem.
: Workaround: Enter the ip host-routing command before attempting a TFTP download.

CSCdj42967

: Symptom: When memory is almost or completely exhausted and a soft PVC goes down, it might not come back up, leaving it in a releasing or inactive state.
: Workaround: None.

CSCdj54954

: Symptom: In an LightStream 1010 ATM switch equipped with an FC-PFQ, the maximum number of cells available for use is 64511. The number of cells in the switch fabric is 65535.
: Workaround: None.

CSCdj59621

: Symptom: The system does not support CUGs on soft PVC connections. For example, if you define a set of access policies and a CUG on an interface with the PVC leg of a soft PVC call, the CUG parameters do not apply to those calls.
: Workaround: None.

CSCdj59640

: Symptom: When running a test between two CES ports, AIS problems might occur when a CES DSX1 loopback payload is activated.
: Workaround: None.

CSCdj71109

: Symptom: The LightStream 1010 switch does not currently support maxvc-number negotiation through ILMI.
: Workaround: None.

CSCdj71876

: Symptom: Under some rare conditions (not yet identified), some ports might stick in the WaitDevType state.
: Workaround: Reboot the switch.

CSCdj74422

: Symptom: When a LightStream 1010switch running Cisco IOS Release 11.3 is connected to another running Cisco IOS Release 11.2, and it tries to allocate VCI to equal 32(VCI=32), the LightStream1010 switch running Cisco IOS release 11.3 does not accept the value because the VCI values 32, 33, and 34 are reserved in Cisco IOS Release 11.3 and later.
: In this case, the call will not succeed for the first three attempts, and will only succeed once the vpi/vci assignments increment to 35. There are no operational problems with this caveat.
: Workaround: Configure atmfAtmLayerMinSvccVci to 32 on the switch running Cisco IOS Release 11.3.

CSCdj78305

: Symptom: When IP host routing is enabled and saved to NVRAM, the only way to remove this command from the configuration is to enable and disable IP routing in Cisco IOS Release 11.3 (0.8) TWA4(2).
: Workaround: None.

CSCdj82930

: Symptom: OSPF does not recognize more than four parallel interfaces causing some tag VCs (TVCs) to not getting switched to other interfaces if a tunnel carrying the TVCs is shutdown.
: Workaround: Enter the clear ip route command on the switch on the interface that was shut, or a clear ip route command on all the switches seems to bring everything back up most of the time. If the clear ip route command does not work, enter a shut/no shut command on the UNI interfaces on the switch on which the physical interface was shut to bring everything back up.

CSCdj84344

: Symptom: There is a small divergence in the measured output of the shaped VP tunnels at rates of 90 Mbps and above.
: Workaround: None.

CSCdj84379

: Symptom: The granularity provided by the FC-PFQ feature card scheduling hardware does not allow an exact match of all requested cell rates. To satisfy the traffic contract guarantee, the next higher available scheduling value is used. A shaped VP tunnel is used frequently to pass data to a WAN VP trunk, and limits the traffic transmitted to the scheduled rate. This can cause cells to be dropped in the WAN. Any dropping must be done prior to multiplexing onto the VP, so that a packet discard can be performed.
: Workaround: Refer to the information in the DDTs for information on how to make the conversion of a requested rate to the actual rate.

CSCdj85627

: Symptom: A CES PVC cannot be cross connected to a VP tunnel interface.
: Workaround: Use CES soft-VCs instead; a soft CES VC will connect to a tunnel interface.

CSCdj85853

: Symptom: When you set the ROM monitor environment variable boot to a non existent file (using the Cisco IOS command boot system flash) and the configuration register is set to 0x2102 (autoboot), the switch hangs during the subsequent reload command issued by the software.
: Workaround: Power-cycle the switch; a break character is sent to the switch to force it to the ROM monitor prompt. You can then manually reboot the switch.

CSCdj86073

: Symptom: The following messages might appear on the LightStream 1010 console:
: SYS-3-MGDTIMER Unitialized timer
: This message is harmless and no loss of function occurs.
: Workaround: None.

CSCdj87463

: Symptom: The CBR interface on the CES port adapter is always in the up/up state, even when no cable is attached, unless it is administratively shut down. If the CBR line goes down, the interface stays up/up, and the only error reported is a Linestate: LossOfSignal.
: Workaround: Administratively shut down the interface.

CSCdj88091

: Symptom: An ATM signaling SETUP message progressing through the switch does not automatically negotiate-down the PCR to the minimum line rate through which the SETUP passes.
: This occurs if the SETUP enters the switch via a NNI interface. If the SETUP enters the switch via a UNI 4.0 interface, the PCR to the minimum line rate negotiation is performed.
: Workaround: None.

CSCdj89223

: Symptom: PNNI support of left justified E.164 AESA addresses is not available in Cisco IOS Cisco IOS Release 11.3 (0.8)TWA4(4) release. This feature will be released at the next maintenance release.
: Workaround: None.

The maximum number of ELAN LES/BUS pairs that the ASP ATM interface supports is 10.

Cisco IOS Release 11.2(8.0.1)FWA4(1) Caveats Corrected

This section describes caveats from Cisco IOS Release 11.2(8)WA3(3) that have been corrected by Release 11.2(8.0.1)FWA4(1) of the LightStream 1010 ATM switch software.

CSCdj02004

: Symptom: Under some circumstances, the Ethernet port on the LightStream 1010 ATM switch hangs. When you enter the show interface ethernet 2/0/0 command, the interface is shown up, but the output queue is full.

CSCdj48371

: Symptom: The ATM accounting periodic collection writes more records than the number of VCs it is monitoring.

CSCdj48158

: Symptom: The clear counters command can cause a T1 frame slip on the CES ports.

CSCdj49255

: Symptom: For PVPs, virtual path identifier (VPI)=0 is not allowed. This restriction has been relaxed for the hard transit PVPs.

CSCdj51042

: Symptom: On 25-Mbps port adapters, entering the show atm vc command can potentially crash the switch.

CSCdj50993

: Symptom: There is a memory leak in Cisco IOS Release 11.2.8.

CSCdj63058

: Symptom: The Service Specific Connection Oriented Protocol (SSCOP) layer sequence number wraparound condition leads to memory leaks and memory fragmentation problems. The problem occurs when the SSCOP's send sequence number reaches a maximum value of 16777215. You must reset the switch to restore normal functionality.

CSCdi72017

: Symptom: The switch does not support restart based on the virtual path identifier/virtual channel identifier (VPI/VCI).

CSCdi74298

: Symptom: When a reload is entered, the following message might appear.

%ALIGN-3-SPURIOUS: Spurious memory access made at 0x600D2EBC reading 0x0

: This caveat does not affect the operation of the switch.

CSCdi85540

: Symptom: Logical multicasting is not supported.

CSCdi93291

: Symptom: A DS3 port adapter alarm indication signal (AIS) is not sent from a shutdown port when reloading the switch software. This might cause one side of a link to appear up and the other side of a link to appear down. It only occurs if one side of the link is shut down during a power-up cycle. If the interface is brought up, both sides of the link resume normal operation.

CSCdj03281

: Symptom: If a T1/E1 port is configured as the clock source for the system, and the port receives transitions in link status that affect the clock, other interfaces that derive their clock from that clock source might go down for a moment. This occurs only when transitions are less than one second.

CSCdj03621

: Symptom: The receive cell counter on the virtual circuit VPI=0, VCI=32 displays erroneous cell counts.

CSCdj04898

: Symptom: The SNMP agent on the switch always returns a "Slot empty" value, even if a Flash memory card is present in the Personal Computer Memory Card International Association (PCMCIA) slot.

CSCdj13326

: Symptom: ATM accounting background notification is not supported.

CSCdj22451

: Symptom: The LightStream 1010 ATM switch might log the following message:

%SYS-3-MGDTIMER:Uninitialized timer, timer stop, timer = [hex].

: This message does not affect the switch operation.

CSCdj41665

: Symptom: If you hot swap a T1/E1 port adapter with an OC3 port adapter, the switch might hang.

CSCdj41709

: Symptom: The TTB length bit is not set for G832 framing. The TTB messages, which check for the continued presence of the intended transmitter, must be enabled for G832Adm framing.

Cisco IOS Release 11.2(8.0.1)FWA4(1) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch for Cisco IOS Release 11.2(8.0.1)FWA4(1).

The following caveats have been identified for this release of the LightStream 1010 ATM switch software:

CSCdi55937

: Symptom: Remote defect identification (RDI) cells sent by an end point in response to alarm indication signal (AIS) cells generated at an intermediate switch with a fault condition on an interface are not propagated beyond the intermediate switch. The intermediate switch removes the connection leg entries for both interfaces participating in the connection when a fault is discovered on one of the interfaces, even though the other interface might still be up. As a result, the RDI cells are dropped at the intermediate switch.
: Workaround: None.

CSCdi72255

: Symptom: E3 port adapters are limited to 65535 cells per second per PVC regardless of the framing type. There is no benefit from G832 framing.
: Workaround: None.

CSCdi74229

: Symptom: When more than 1000 SVCs are active on an interface and the shutdown command is entered, all SVCs on that interface are released and the following message appears:

%SYS-3-CPUHOG

: This message indicates that the release process runs for a long time before returning control to the kernel, which can then schedule other tasks. This process does not affect normal operation of the switch.
: Workaround: None.

CSCdi75584

: Symptom: Under very heavy traffic conditions the switch might experience temporary queue cell failures. This should clear after the traffic congestion clears.
: Workaround: None.

CSCdi82954

: Symptom: The receiver circuitry on DS3 port adapters can interpret noise as a valid signal. This signal is framed incorrectly and does not contain real data. The DS3 controller interprets the signal as a bad signal instead of no signal, and the red RX light emitting diode (LED) lights up.
: Workaround: None.

CSCdi83275

: Symptom: When a large number of LANE clients come up and down constantly over extended periods of time, the system can run out of AAL5 buffers and the following message appears:

%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts

: In most cases, the system continues to function normally, but occasionally the system denies additional calls from end systems.
: Workaround: Toggle the interface to reinitialize all connections and restore normal operation.

CSCdi83567

: Symptom: When an AddParty message is sent across an E.164 interface, and the message does not include the CallingPartyAddress information element, the AddParty request is rejected on the first attempt. The second attempt is successful.
: Workaround: Include the CallingPartyAddress information element in the AddParty message.

CSCdi92142

: Symptom: A LECS, using Cisco IOS Release 11.2(X), expects all LESs to establish an individual control VC to the LECS in order to validate clients.
: If different Emulated Local Area Networks (ELANs), using Cisco IOS Version 11.1(X), on multiple subinterfaces of the same physical interface, then all LES(s) multiplex the control messages (which validate the clients) into a single VC.
: For example, see the following LES router configuration:

atm1/0.1    sysa_70k_31_a1.1_LAN sysa_70k_31_a1.1_LAN
atm1/0.2    sysa_70k_31_a1.2_LAN sysa_70k_31_a1.2_LAN
atm1/0.3    sysa_70k_31_a1.3_LAN sysa_70k_31_a1.3_LAN
atm1/0.4    sysa_70k_31_a1.4_LAN sysa_70k_31_a1.4_LAN

: This configuration of an LECS sends the following warning messages to the console stating that an LES of one ELAN is attempting to obtain information about another ELAN:

%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.1_LAN'
%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.2_LAN'
%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 
'sysa_70k_31_a1.3_LAN'

: The clients are still allowed to join the ELAN. Disregard the warning message.
: Workaround: None.

CSCdj01016

VBR: sustained cell rate (SCR) + sustained-cell-rate-margin-factor x (PCR - SCR).
ABR, UBR: no bandwidth is allocated.

Workaround: None.

CSCdj01757

: Symptom: When one of the installed power supplies is powered OFF, and you are copying an image to bootflash, a power supply failure message appears.
: Workaround: None.

CSCdj03229

: Symptom: A DS3 interface connected to a Cisco BPX switch occasionally goes down and back up after you enter the no shutdown command. The interface operates normally after it comes up the second time.
: Workaround: None.

CSCdj10889

: Symptom: The call attempt counters for PortSelectGroups might not count the outgoing calls on its NNI interfaces because of switch crankback attempts. This might result in a discrepancy between the call attempt counters shown on Portselgroup representing the interface on which the call came in and the counters shown on the PortSelgroup representing the interface over which an attempt was made to forward the call. This problem might occur when a call fails.
: Workaround: None.

CSCdj11070

: Symptom: If you disable Cisco Discovery Protocol (CDP) on the 2/0/0.x interface and it is configured as a LEC, the information is not saved to NVRAM when you enter the copy running-config startup-config command. CDP is disabled in the running configuration, but it reenabled after a system reload.
: Workaround: None.

CSCdj12108

: Symptom: This caveat is caused by a compiler bug. The bug corrupts the stack and eventually crashes while calling find_buddy repeatedly. A watchdog timeout then causes a reload.
: Workaround: None.

CSCdj13565

: Symptom: ATM RMON data collection is not supported on subinterfaces or tunnels. The atm rmon collect command is accepted on hardware interfaces only; it is ignored on subinterfaces. SNMP and NVGEN support (via portSelTable) is not possible until the interfaces MIB (RFC 1573) entries are added for tunnel subinterfaces. ATM RMON counters for a hardware interface do not include any of the traffic through tunnels configured on the interface.
: Workaround: None.

CSCdj18430

: Symptom: The cell count reported on a snooped interface is twice the actual number of cells transmitted.
: Workaround: None.

CSCdj18678

: Symptom: SNMP support of the ciscoAtmIfPhysEntryData table and LED information is not available on the 25-MB port adapter.
: Workaround: None.

CSCdj24272

: Symptom: The system restarts when you enter the no shutdown command on an E3 interface when the port adapter is not installed.
: Workaround: None.

CSCdj25772

: Symptom: Cell loss might occur while hot swapping a power supply.
: Workaround: None.

CSCdj28496

: Symptom: The fail over time for the circuit emulation switch (CES) soft VC on a redundant link might be inconsistent, from less than 1 second up to 15 seconds.
: Workaround: None.

CSCdj32484

: Symptom: A TFTP download to a LightStream 1010 ATM switch might fail because of an ARP table corruption problem.
: Workaround: Enter the ip host-routing command before attempting a TFTP download.

CSCdj42070

: Symptom: Spurious memory access messages appear when you enter the debug atm packet command on one of the interfaces of the LightStream 1010 ATM switch.
: Workaround: None.

CSCdj42967

: Symptom: When memory is almost or completely exhausted and a soft PVC goes down, it might not come back up.
: Workaround: None.

CSCdj50627

: Symptom: With multiple LES/BUS pairs configured on a LightStream 1010 ATM switch and about 20 LECs configured to join the ELANs, repeated shutdown or no shutdown of the interface for an extended time could produce the following error message:

ATMS2000_add_party_to_output_only_errors

: Workaround: None.

CSCdj53797

: Symptom: The system sends out excessive ARPs on the Ethernet interface when ip host-routing is enabled.
: Workaround: None.

CSCdj54954

: Symptom: In an LightStream 1010 ATM switch equipped with a FC-PFQ, the maximum number of cells available for use is 64511. The number of cells in the switch fabric is 65535.
: Workaround: None.

CSCdj56808

: Symptom: When you set multiple VP tunnels between the same neighbor, PNNI does not switch to a better tunnel for flooding when an alternate is possible. Using a VP tunnel that has less tolerance for CDV causes cell drops and a failure to complete database synchronization.
: Workaround: None.

CSCdj57479

: Symptom: When you configure LES/BUS LANE service on the CPU port, and there is heavy signalling traffic, usually when the switch resets and tries to come back up with a large number of clients for each LES/BUS, the following warning message appears:

CPUHOG - atmsig_output

: This has no impact on the system functionality or performance.
: Workaround: None.

CSCdj59621

: Symptom: The system does not support CUGs on soft PVC connections. For example, if you define a set of access policies and a CUG on an interface with the PVC leg of a soft PVC call, the CUG parameters do not apply to those calls.
: Workaround: None.

CSCdj59640

: Symptom: When running a test between two CES ports, AIS problems might occur when a CES DSX1 loopback payload is activated.
: Workaround: None.

CSCdj70489

: Symptom: You can configure the LightStream 1010 switch for a core-dump using FTP. This is caused because the FTP subsystem is not included in the LightStream 1010 image. This caveat was first found in Cisco IOS Release 11.2 (8.0.1).
: Workaround: None.

CSCdj71109

: Symptom: The LightStream 1010 switch does not support maxvc-number negotiation through ILMI.
: Workaround: None.

CSCdj71876

: Symptom: Under some rare conditions (not yet identified), some ports might stick in the WaitDevType state.
: Workaround: Reboot the switch.

CSCdj74422

: Symptom: When a LightStream 1010 switch running Cisco IOS Release 11.2 is connected to another running Cisco IOS Release 11.3, and the switch running Cisco IOS Release 11.2 tries to allocate vci to equal 32 (vci=32), the switch running 11.3 does not accept the value, because the vci values 32, 33, and 34 are reserved in Cisco IOS Release 11.3 and later. In this case the call will not succeed for the first three attempts, and will only succeed once the vpi/vci assignments has incremented to 35. There are no operational problems with this caveat.
: Workaround: Configure atmfAtmLayerMinSvccVci to 32 on the switch running Cisco IOS Release 11.3.

CSCdj78305

: Symptom: When IP host routing is enabled and saved to NVRAM, the only way to remove this command from the configuration is to delete and rebuild the NVRAM in Cisco IOS Release 11.2 (8.0.1) FWA4(1).
: Workaround: None.

CSCdj81680

: Symptom: OAM cells with invalid type are passed through the --switch rather than being discarded.
: Workaround: None.

CSCdj84656

: Symptom: Globally disabling ATM accounting did not turn off file_full traps.
: Workaround: None.

CSCdj85627

: Symptom: A CES PVC cannot be cross-connected to a tunnel interface.
: Workaround: Use CES soft-VCs instead; a soft CES VC will connect to a tunnel interface.

CSCdj85853

: Symptom: When the ROM monitor environment variable boot is set to a non-existent file (using the boot system flash command) and if the configuration register is set to 0x2102 (autoboot), the switch hangs during the subsequent reload command issued by the software.
: Workaround: Power-cycle the switch, a break character is sent to the switch to force it to the rom monitor prompt. The switch can then be manually re-booted.

CSCdj86073

: Symptom: The following messages might appear on the LightStream 1010 console:
: SYS-3-MGDTIMER Unitialized timer
: This message is harmless and no loss of function occurs.
: Workaround: None.

CSCdj88091

: Symptom: An ATM signalling SETUP message progressing through the switch does not automatically negotiate-down the peak cell rate (PCR) to the minimum line rate through which the SETUP passes.
: This occurs if the SETUP enters the switch via a NNI interface. If the SETUP enters the switch via a UNI 4.0 interface, such negotiation is performed.
: Workaround: None.

The maximum number of ELAN LES/BUS pairs that the ASP ATM interface supports is 10.
