Cisco IOS Release 11.2(15)WA3(7)
Release Notes for LightStream 1010 ATM Switch Software

January 7, 1999

LightStream 1010 ATM Release 11.2(15)WA3(7)

This release note describes the features and caveats for Cisco  IOS Release  11.2(15)WA3(7) for the LightStream  1010 ATM switch software. The LightStream  1010 ATM switch software is based on Cisco IOS Release 11.2(15).

Contents

This release note includes the following sections:

Introduction

The LightStream  1010 ATM switch provides ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers. The ATM switch uses fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.

Note The ATM switch and port adapters can be installed in the Catalyst  5000 switch chassis.

System Requirements

This section describes the system requirements for Release 11.2(15) and includes the following sections:

Memory Requirements

The system Dynamic Random Access Memory (DRAM) resides on a SIMM module on the ATM switch. The default DRAM configuration is 16  MB. The amount of DRAM required on the ATM switch module is determined by both the number of active physical and logical ports (virtual path tunnels) and the number of active switched virtual channels (SVCs) through the switch.

Table 1 provides an approximate guide to use when determining the amount of DRAM required for a switch with 32 physical ports.


Table 1:
SVCs Required DRAM Required

Less than 4000 active SVCs

16-MB DRAM

Between 4000 and 16,000 active SVCs

32-MB DRAM

Between 16,000 and 32,000 active SVCs

64-MB DRAM

DRAM Required Determined by SVCs

Hardware Supported

This section describes the software and associated hardware supported for the LightStream 1010 ATM switch.

The software is based on Cisco IOS Release 11.1 on April 1, 1998. This software base is superseded by the WAS3 and WAS4 releases.

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

Table 2 lists the release names, versions, and part numbers used with the LightStream 1010 ATM switch.

Release 11.2(15)WA3(7) Caveats Corrected

This section describes caveats that have been corrected by Release 11.2(15)WA3(7) for the LightStream 1010 ATM switch.

Release 11.2(15)WA3(7) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch for Release 11.2(12)WA3(7).

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

%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts
The system continues to function, in most instances, but might stop accepting any more calls from the end systems.
Workaround
If the switch does not bring up more calls, toggling an interface might help to reinitialize all the connections and bring the system back to working condition.
[CSCdi83275]
Workaround
The normal mode of operation is to include the CallingPartyAddress information element in the AddParty message.
[CSCdi83567]
If different Emulated Local Area Networks (ELANs), using Cisco IOS Version 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, using 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.
[CSCdi92142]
Workaround
Ensure that the interface is not shut down during a switch software reload.
[CSCdi93291]
[CSCdj01016]
The call attempt counters for PortSelectGroups might not count the outgoing calls on its NNI interfaces due to switch crankback attempts. This might cause a discrepancy between the call attempt counters shown on the following:
This might be more evident when a call fails to be established.
[CSCdj10889]
Support for ATM accounting background notifications is provided in the next maintenance release.
[CSCdj13326]
Workaround
Install a PCMCIA flash card with a valid IOS image.
[CSCdk48527]
If the config-register is set to 0x2102, the switch crashes a second time by bus error while trying to open slot 0. The switch then recovers and boots the bootflash image.
Workaround
Set the MONRC command in the rom monitor, which overrides any BOOT SYSTEM command from the configuration, as follows:
rommon 1>MONRC="boot bootflash:"
rommon 2>sync
rommon 3>reset
[CSCdk64928]

Release 11.2(15)WA3(6) Caveats Corrected

This section describes caveats that have been corrected by Release 11.2(15)WA3(6) for the LightStream 1010 ATM switch.

Using fast-retry, each VC is released. Using slow-retry, after the soft-vc retry timer (180s) expired, the SETUP message is no longer rejected.
[CSCdj95371]
If the LANE clients try to join the ELAN, they are rejected.
[CSCdk08318]

Release 11.2(15)WA3(6) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch using Release 11.2(12)WA3(6).

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

%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts
The system continues to function, in most instances, but might stop accepting any more calls from the end systems.

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.

Release 11.2(12)WA3(5) Caveats Corrected

This section describes caveats that have been corrected by Release 11.2(12)WA3(5) for the LightStream 1010 ATM switch.

Workaround
Do not turn on ip host-routing.
[CSCdj53797]

Release 11.2(12)WA3(5) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch for Release 11.2(12)WA3(5).

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

Workaround
Use CES soft-VCs instead; a soft CES VC connects to a tunnel interface.
[CSCdj85627]
Workaround
Modify the ATM ILMI keepalive timer to less than 5 seconds.
[CSCdj90806]
Using fast-retry, each VC is released. Using slow-retry, after the soft-vc retry timer (180s) expired, the SETUP message is no longer rejected.
[CSCdj95371]
If the LANE clients try to join the ELAN, they are rejected
[CSCdk08318]
If different Emulated Local Area Networks (ELANs), using Cisco IOS Version  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.

Caveats and Caveats Corrected For Release 11.2(8)WA3(3) and 11.2(5)WA3(2b)

Releases before this one assumed that in each priority level the default clock (if none was configured) was the system clock (ATM switch reference). With this release no defaults are assumed. A clock at a priority that is not configured specifies "no clock." When clock switch over occurs, the software will switch to the next highest-configured priority network clock source and skip priorities that are not configured.

This section contains listings of the caveats and corrected caveats for these releases. These caveats are described in detail in the following sections:

Release 11.2(8)WA3(3) Caveats Corrected

This section describes caveats that have been corrected by Release 11.2(8)WA3(3) for the LightStream 1010 ATM switch.

Modifications and Caveats For Release 11.2(2)WA3(1a)

The following clock selection changes listed in Table 9 apply to release 11.2(2)WA3(1a).


Table 9: Clock Selection Changes for Release 11.2(2)WA3(1a)
Clock Mode Release 11.1 Release 11.2

Network Derived

Derives clock from the port selected as the network clock at the highest priority. This can be the ATM switch if all clocks are bad or there was no selection.

If no selection for network-clock-select has been made the clock defaults to the ATM switch (default).

Free-running

Uses the ATM switch clock (default).

Uses the port local oscillator on the port adapter when available.

Loop-timed

Uses the clock derived from the receive side.

Uses the clock derived from the receive side.

In the 11.2 release, the default clock selected on any port was changed. The default mode is network-derived. If no port is selected as the source of the network clock, the default is the system clock supplied by the ATM switch. In the 11.1 release, if no clock source was specified for a port, the clock mode default was free-running, internally equivalent to selecting the system clock supplied by the ATM switch. The defaults are not saved in the configuration.

If you changed the default in 11.1 to network-derived when upgrading to Release 11.2 because network-derived is the default, the clock mode remains the same. However, if you move back to Release 11.1, that port reverts to the free-running (with ATM switch) clock default configuration. If you want network-derived clock you must reconfigure the port.

Release 11.2(2)WA3(1a) Caveats

This section describes unsupported features and limitations, caveats, and some potentially unexpected behavior by the LightStream 1010 ATM switch for Release 11.2(2)WA3(1a).

The following features are not supported in this release (even though the commands might be visible in the command-line interface):

Support for these features is expected in a subsequent release.

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