Release Notes for Catalyst 5000 Family ATM Module Release 12.0W5

Release Notes for Catalyst 5000 Family ATM Module Release 12.0W5

August 4, 2000

These release notes describe the Catalyst 5000 family ATM module release 12.0(10)W5(18a).

Note The Catalyst 5000 family includes the Catalyst 5002, the Catalyst 5000, the Catalyst 5505, the Catalyst 5509, and the Catalyst 5500 switches. Throughout this publication and all Catalyst 5000 family documents, the phrase Catalyst 5000 family switches refers to all Catalyst 5000 family switches, unless otherwise noted.

The following modules are supported in this release:

The ATM dual PHY OC-3 modules (WS-X5153, WS-X5154, WS-X5155, WS-X5156, WS-X5157, and WS-X5158) use the c5atm-wl-mz image. These modules do not support Multiprotocol over ATM (MPOA). This image supports LAN Emulation (LANE) and RFC 1483 non-traffic-shaping permanent virtual connections (PVCs). If you want traffic-shaping PVC functionality, use the c5atm-wt-mz image.

The ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162), the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168), and the ATM Fabric Integration module (WS-X5165) use the c5atm-lc-mz image. These modules support MPOA, LANE, and RFC 1483 with traffic shaping. The same software image supports all three features.

Usage Guidelines and Restrictions

This section describes the usage guidelines and restrictions for the Catalyst 5000 family release 12.0W5.

All three versions are identical.
Note The set clock command is not supported by the ATM Fabric Integration module.

Software Release 12.0(10)W5(18a)

Software release 12.0(10)W5(18a) supports PVC traffic shaping on the Catalyst 5000 ATM modules. Software release 12.0(10)W5(18a) is the first maintenance release for the PVC traffic-shaping feature supported on the Catalyst 5000 ATM modules since software release 11.3(6)WA4(9d).

Software Release 12.0(9)W5(17a)

No new features were introduced in software release 12.0(9)W5(17a).

Software Release 12.0(9)W5(17)

No new features were introduced in software release 12.0(9)W5(17).

Software Release 12.0(7)W5(15b)

No new features were introduced in software release 12.0(7)W5(15b).

Software Release 12.0(4a)W5(10)

This section contains new feature information, usage guidelines, and restrictions for release 12.0(4a)W5(10).

New Features

Release 12.0(4a)W5(10) supports these new features:

FSSRP

FSSRP differs from the current Simple Server Redundancy Protocol (SSRP) in that all configured LAN Emulation Servers (LESs) (master LES as well as the secondary LESs) of an Emulated LAN (ELAN) can accept join requests from any FSSRP-aware client. The benefit of establishing connections with all the LES and Broadcast and Unknown Server(BUS) pairs is that a LEC can switch over to a new LES/BUS, in the event of a failure, without any noticeable delay. The fast switchover is made possible by handing out all the configured LES addresses (in the order in which they are configured) to the LAN Emulation Clients (LECs) in the configuration response through a Cisco proprietary type-length-value (TLV). Note that the list of configured LES addresses includes the LES address that is also returned in the configuration response. This list includes all the FSSRP-capable LES addresses and an old-style LES (if that is the master LES). This list includes a maximum of four addresses.

Note Third-party LANE clients or FSSRP-unaware (Cisco) clients cannot take advantage of the multiple LES addresses. In the 11.3 software train, release 11.3(8)WA4(11a) or later is compatible with FSSRP.

LECs are allowed to join an FSSRP LES by including the FSSRP TLV in the join request, which uniquely identifies the capability of the client to the LES. The master LES also keeps track of any FSSRP-unaware clients that have joined the ELAN and redirects these clients to a new master LES in the event of a switchover (a preempt configuration). With FSSRP implemented, only FSSRP-unaware clients need to go to LECS to get the new (master) LES address and rejoin the ELAN. All LESs know if they are the master LES or a secondary LES.

There is only one new command for this feature. Use the lane fssrp to enable FSSRP.

Description

Use the lane fssrp command from the major interface configuration level to enable all LES, LEC, and BUS on the subinterfaces configured on that major interface.

lane fssrp

Default

By default, FSSRP is not enabled.

Command Type

IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

When you enable FSSRP on a major interface, all LECs and LES/BUS pairs configured on the subinterfaces of that major interface become FSSRP enabled.

Example

This example shows how to enable FSSRP on the major interface:

ATM#config term
Enter configuration commands, one per line.  End with CNTL/Z.
ATM(config)#interface atm0
ATM(config-if)#lane fssrp
ATM(config-if)#
ATM#

There are also modifications to the show lane client display output:

Fast PHY Switchover

In previous releases, when switching from the active PHY to the redundant PHY, the link went down on all the LECs and a message was sent to the Catalyst 5000 family supervisor engine for every VLAN configured on the module. This operation updated the spanning tree in the supervisor engine. After the redundant PHY became the active PHY, new LECs were created and a message was sent to the supervisor engine for every VLAN. While these changes were taking place, traffic was stopped.

With Release 12.0(4a)W5(10), fast PHY switchover reduces the time to restore traffic flow when traffic switches from the active PHY to the redundant PHY in the Catalyst 5000 dual PHY ATM modules.

There are no new or modified commands for this feature.

Resolved Caveats in Software Release 12.0(9)W5(17a)

This section describes the open caveats in Release 12.0(9)W5(17a).

The vulnerability, identified as Cisco bug ID CSCdr36952, affects virtually all mainstream Cisco routers and switches running Cisco IOS Release 11.1 through Release 12.1. The vulnerability has been corrected and Cisco is making fixed versions available to replace all affected Cisco IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect.
Workaround: Nullify the vulnerability by disabling the Cisco IOS HTTP server, by preventing access to the port in use by the HTTP server on the affected router or switch, or by applying an access-class option to the service itself. The IOS HTTP server is not enabled by default except on a small number of router models in specific circumstances.
Please see http://www.cisco.com/warp/public/707/ioshttpserver-pub.shtml for the latest complete version of this security advisory. (CSCdr36952)

The workaround is to limit the number of LES/BUS pairs per LANE module to 30. (CSCdp11306)

Resolved Caveats in Software Release 12.0(7)W5(15b)

This section describes the open caveats in Release 12.0(7)W5(15b).

When the LECS is brought down, some of the LECs lose their connections to some of the servers. This might result in the LECs going down when the LECS comes up again even if FSSRP is enabled. This problem is resolved in software release 12.0(7)W5(15b). (CSCdp25461)
In some situations an LES receives a configuration response with the FSSRP TLV not containing its address. This causes the LES to tear down all its connections, which might bring down a LEC. This problem is resolved in software release 12.0(7)W5(15b). (CSCdp66265)
This happens because when the shutdown and no shutdown commands are performed on a subinterface, any configured PVCs are deleted and recreated. As a result, the PVCs lose their bindings to VLANs. The only workaround is to enter the atm pvc vlan command to manually create the PVC-to-VLAN bindings.
We recommend that you configure PVCs on the major interfaces. If you configure PVCs on subinterfaces, we recommend that you do not perform shutdown and no shutdown commands on the subinterfaces. This problem is resolved in software release 12.0(7)W5(15b) (CSCdk76407)
On a Catalyst 5000 ATM line card, PVCs cannot be created using the multi-step process defined in CISCO-ATM-PVC-MIB. This problem is resolved in software release 12.0(7)W5(15b) (CSCdk63703) (CSCdp26510)
This problem is caused by Fast-PHY switchover. When LAN client is removed and then too quickly configured again, the port status change does not take place. The LEC comes up with spanning tree in blocked state, but the supervisor engine does not move the LEC port into forwarding state. This problem is resolved in software release 12.0(7)W5(15b) (CSCdm60158)
In some cases, an LE-ARP may be requested for a MAC address when a MAC address already exists. This problem is resolved in software release 12.0(7)W5(15b) (CSCdm61379)
The following message may appear on the screen when there are more than 4000 ingress/egress caches:
%SYS-3-CPUHOG:Task ran for 3060 msec (0/0), process =
MPOA Client, PC = 40095C82.
This message is just a warning. This problem is resolved in software release 12.0(7)W5(15b) (CSCdm87739)
This problem is resolved in software release 12.0(7)W5(15b) (CSCdp01039)
If a LEC is blocked, no data should be switched on this interface. But due to this bug, the MPC bound on this subinterface is still working and MPOA packets are still switched. This problem is resolved in software release 12.0(7)W5(15b) (CSCdp04835)
The atm PVC bind command reappears after it is deleted when the fiber connection is disconnected and then reconnected again. This problem is resolved in software release 12.0(7)W5(15b) (CSCdp07158)
When an MPS has been removed but packets are still arriving destined for that MPS, the following error message displays:
%MPOA-3-MPC_ERROR:mpc_process_flow_t:imac from cookie 258 not found
This error message is generated because the transmit host is not aware that the MPS has been removed. The error message disappears after the transmit host learns of the MPS configuration change. (CSCdp80442)
If only LANE is configured and if the LEC LECID is not zero, the system runs out of memory and crashes. This problem is resolved in software release 12.0(7)W5(15b) (CSCdp12241)
A problem with the compare routine causes the egress cache to be out of order. This may cause the system to crash. This problem is resolved in software release 12.0(7)W5(15b) (CSCdp16491)
The Catalyst 5000 ATM line card does not provide the ATM switch connected to it with the supervisor engine IP address. This problem is resolved in software release 12.0(7)W5(15b) (CSCdp34774)

Open Caveats in Release 12(4a)W5(10)

This section describes open caveats in Release 12.0(4a)W5(10).

This happens because when the shutdown and no shutdown commands are performed on a subinterface, any configured PVCs are deleted and recreated. As a result, the PVCs lose their bindings to VLANs. The only workaround is to enter the atm pvc vlan command to manually create the PVC-to-VLAN bindings.
We recommend that you configure PVCs on the major interfaces. If you configure PVCs on subinterfaces, we recommend that you do not perform shutdown and no shutdown commands on the subinterfaces. (CSCdk76407)

Available 24 hours a day, 7 days a week, CCO provides a wealth of standard and value-added services to Cisco's customers and business partners. CCO services include product information, product documentation, software updates, release notes, technical tips, the Bug Navigator, configuration notes, brochures, descriptions of service offerings, and download access to public and authorized files.

CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously: a character-based version and a multimedia version that resides on the World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.

You can access CCO in the following ways:

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
