Problem Description

Catalyst 6000 release 5.3(1a)CSX has been removed from Cisco Connection Online (CCO) due to an incompatibility with the ASIC Centauri revision 1.2. Catalyst release 5.3(1a) will continue to be supported with the ASIC Centauri revision 1.1.

Problem Symptoms

Following replacement of a Catalyst 6000 supervisor, some quality of service (QoS) functionality does not function properly (for example, aggregate policing with mark). The Catalyst release 5.3(1a)CSX is running on this system.

The show qos policer config all command indicates an aggregate policer present, but the show qos policer runtime aggregate command does not list any current runtime information.


Compatibility problems were isolated by Cisco development between the ASIC Centauri revision 1.2 and the Catalyst release 5.3(1a)CSX. The Catalyst release 5.3(1a)CSX has been removed from CCO, but not deferred. It will continue to be supported with ASIC Centauri revision 1.1.

ASIC Centauri revision 1.2 is supported by Catalyst releases 5.3(2)CSX and later.

For more information, see the Release Notes for Catalyst 6000 Family Software Release 5.x.

The current ASIC Centauri revision can be viewed by entering the show module command at the Catalyst 6XXX command line. The revision numbers are listed at the bottom of the show module output.


1_____L3 Switching Engine_WS-F6K-PFC__SAD03322508__1.2 

In this example, 1.2 is the ASIC Centauri revision.


When using Catalyst release 5.3(1a)CSX, make certain the ASIC Centauri revision is 1.1. If your ASIC Centauri revision is 1.2, upgrade the software to Catalyst release 5.3(2)CSX to fix any QoS functionality problems.

If you are a registered CCO user and you have logged in, you may download Catalyst release 5.3(2)CSX from CCO (registered customers only) .
