10 Release Notes for Catalyst 6000 Family Software Release 5.x
Open and Resolved Caveats in Software Release 5.3(4)CSX
The fix involves performing an intermediate step, clearing the ACL mapping on the ports that
have a different ACL mapping than the other ports, and mapping them to all have the same ACL
before trying to channel them together (it is important to clear the older mapping first).
— set port qos 4/1 policy local
— set qos acl map acl1 4/1
— set qos policy cops
— clear qos acl map acl1 4/1
— set port qos 4/1 policy cops
— set port channel 4/1-8 des

• Rapidly disabling and enabling QoS with the policy source set to COPS might cause the switch
to reset. The workaround is to wait approximately 30 seconds after disabling QoS before
reenabling it when the QoS policy source had been set to COPS. (CSCdp32467)
• Online diagnostic failures are experienced on modules during bring up, online insertion, or
module reset if the QoS default-action MAC ACL is reconfigured to include an aggregate policer
with an action of drop. The system default does not include an aggregate policer in the
default-action MAC ACL. The likelihood of the diagnostics failures increases as the amount of
traffic being policed (dropped) by that aggregate policer increases. In general, as the rate value
specified in the policer decreases and/or the amount of traffic matching all ACLs specifying that
aggregate policer increases. (CSCdp15471)
• After setting the QoS policy source to local, you might need to wait approximately 20 seconds
before the QoS policy source can be set back to COPS. (CSCdp34367)
• After clearing a COPS role or all COPS roles, the console might hang for approximately 20
seconds before showing that the roles cleared. (CSCdp34381)
• Occasionally, when a module is removed before it comes online (and before it is finished running
diagnostics), memory corruption might occur. To avoid this problem, do not remove or reinsert
a module during system power up and do not remove or reinsert a module before it comes online.

• On Catalyst 6000 switches with redundant supervisor engines (MSFC and PFC), after power
cycling the system, some modules might show this message:
LC_DNLD_VERIFY: Error - Checksum verify fail errors.
Note that this bug has no impact and you should ignore these messages. (CSCdp06845)
• When you remove a module and then reinsert a different module, after using the clear config
mod_num command on the newly inserted module, the first port on the module might be shown
as disabled in the port status field. There are two workarounds: 1) Do a second clear config
mod_num. 2) Do a set port enable on the first port. (CSCdp25328)
• On Catalyst 6000 switches with redundant supervisor engines (MSFC and PFC), the following
bus ASIC sequence mismatch might occur during a switchover:
%SYS-1-MOD_SEQMISMATCH:Bus asic sequence mismatch occurred on module 7 (asic=1,
srcidx=0x0, seq=0)
Note that this bug has no impact and you should ignore these messages.(CSCdp25633)
