Release Notes for Catalyst 6000 Family Software Release 5.x 19
Open and Resolved Caveats in Software Release 5.3(2)CSX
• Occasionally after system power up, console display shows minor hardware problem for some
modules. Additionally, after a switchover to the redundant supervisor engine, “Change Status”
messages are displayed. This problem is resolved in software release 5.3(3)CSX. (CSCdp24868)

Open Caveats in Software Release 5.3(2)CSX
This section describes open caveats in supervisor engine software release 5.3(2)CSX.
• Online diagnostic failures are experienced on modules during bringup, 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, that is as the rate
value specified in the policer decreases and/or the amount of traffic matching all ACLs specifying
that aggregate policer increases. (CSCdp15471)
• Changing the console port baud rate from 19,200 to 38,400 incorrectly sets the console port to
9600 baud. After a reset, the console port baud rate is 38,400. Changing the rate to 38,400 from
any other setting works correctly. (CSCdk86876)
• In systems with redundant supervisor engines, occasionally during bootup or after a switchover
to the redundant supervisor engine, a bus ASIC sequence error syslog message is reported to the
console as follows:
%SYS-1-MOD_SEQMISMATCH:Bus asic sequence mismatch occurred on module 8
Additionally, “CentauriInterrupt” and “perseus_intr_hdlr” syslog messages might be generated.
These messages might be generated for some or all installed modules. Ignore these messages.
(CSCdm01334)
• Occasionally, removal or insertion of a module does not generate any SYSLOG messages.
(CSCdm63338)
• The set spantree disable all and enable all commands take 3 to 5 minutes to complete if VTP
pruning is enabled. To avoid the delay, disable VTP pruning before entering the command, and
reenable it after the command is complete. (CSCdm78945)
• If you enable or disable QoS before a module is reported as being online, diagnostics on some
ports on the module may fail. (CSCdm85315)
• The following message should be displayed when you modify the QoS default IP ACL to use the
trust-cos ACE keyword:
Warning: ACL trust-cos should only be used with ports that are also configured with
port trust=trust-cos.
(CSCdm88257)
• A QoS IP ACL can contain nine ACEs that use port operator parameters. If you attempt to add a
tenth QoS IP ACE that uses a port operator parameter to an ACL, the following incorrect message
is displayed:
Cannot configure more than 10 logical operators (gt, lt, eq, neq, range) in an IP ACL.
