Release Notes for Catalyst 6000 Family Software Release 5.x 21

Open and Resolved Caveats in Software Release 5.3(1a)CSX

• ATM-related bug: In a conﬁguration of about 150 VLANs and with a lot of unresolved ARPs on

the ATM module, the supervisor engine complains about the SCP queue being full. This problem

is resolved in software release 5.3(2)CSX. (CSCdp05776)

• ATM-related bug: The ports of the ATM singlemode ﬁber-optic module are not added to the

spanning tree. This problem is resolved in software release 5.3(2)CSX. (CSCdp06550)

• Bus-error exception when a Layer 2 multicast entry is both a multicast protocol conﬁgured entry

and also a user conﬁgured entry. This exception might occur when the multicast protocol is trying

to delete the entry. This problem is resolved in software release 5.3(2)CSX. (CSCdp06796)

• Memory leak might occur if entries were created in alarmTable. This problem is resolved in

software release 5.3(2)CSX. (CSCdp03309)

• Addresses are not learned in some VLANs due to vlan-don’t-learn bit being unintentionally

enabled. This problem is resolved in software release 5.3(2)CSX. (CSCdp00634)

Open and Resolved Caveats in Software Release 5.3(1a)CSX

This section describes open and resolved caveats in supervisor engine software release 5.3(1a)CSX.

Open Caveats in Software Release 5.3(1a)CSX

This section describes open caveats in supervisor engine software release 5.3(1a)CSX:

• 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.
