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

Open and Resolved Caveats in Software Release 5.2(1)CSX

• In systems with redundant supervisor engines, occasionally during bootup or after a switchover

to the redundant supervisor engine, a switching bus sequence error syslog message is reported to

the console as follows:

%SYS-1-MOD_SEQERROR:Switching bus sequence error occurred on module 8

This message might be generated for some or all installed modules. Ignore this message. This

problem is ﬁxed in software release 5.2(1)CSX. (CSCdk81972)

• Occasionally, when you remove an NTP server using the clear ntp server command, the

removed server is not removed from the conﬁguration. The workaround is to reset the switch.

This problem is ﬁxed in software release 5.2(1)CSX. (CSCdk84025)

• In some cases, entering the show cdp neighbors detail command causes the switch to generate

“alignment correction” syslog messages. These messages do not affect the functionality of the

switch. This problem is ﬁxed in software release 5.2(1)CSX. (CSCdk85671)

• Occasionally, attempts to create or modify a VLAN fail with this message:

Vlan configuration failed (41)

The workaround is to reset the switch. This problem is ﬁxed in software release 5.2(1)CSX.

(CSCdk88280)

• When a switching module temperature sensor exceeds its minor threshold, the module’s Status

LED stays green; the Status LED should go to orange. When a switching module temperature

sensor exceeds its major threshold, the module’s Status LED shows green, red, and then stays

green; the Status LED should go to red. This problem is ﬁxed in software release 5.2(1)CSX.

(CSCdk92667)

• If you conﬁgure an EtherChannel between a Catalyst 6000 or 6500 series switch and a Catalyst

5000 series switch, if the EtherChannel formed from ports in desirable mode, a memory leak

occurs on the Catalyst 6000 or 6500 series switch. To avoid the problem, use on mode. This

problem is ﬁxed in software release 5.2(1)CSX. (CSCdk93430)

• If the system message logging level is set to 7 for all facilities, then entering the show logging

buffer command can cause an exception error, causing the switch to reset. This problem is ﬁxed

in software release 5.2(1)CSX. (CSCdk93930)

• On 10/100 or 100 Mbps Ethernet switching modules with multiple ISL trunks, if one or more

trunks goes down, then other ISL trunk ports on the module might not be able to switch ISL

frames longer than 1,443 bytes until all trunks are operational. This problem is ﬁxed in software

release 5.2(1)CSX. (CSCdm10189)

• After a module is reset, the MIB objects under etherStatsEntry (1.3.6.1.2.1.16.1.1) for the

module are removed from etherStatsTable (1.3.6.1.2.1.16.1). To restore the entries, enter set

snmp rmon disable and set snmp rmon enable commands. This problem is ﬁxed in software

release 5.2(1)CSX. (CSCdm10685)

• Occasionally, an exception may occur if an entry in usrHistoryControlTable (1.3.6.1.2.1.16.18.1)

is usrHistoryControlBucketsRequested (1.3.6.1.2.1.16.18.1.1.3) multiplied by

usrHistoryControlObjects (1.3.6.1.2.1.16.18.1.1.2) with a result greater than or equal to

429385320. This problem is ﬁxed in software release 5.2(1)CSX. (CSCdm11328)

• An SNMP query that accesses portTopNControlTable (1.3.6.1.4.1.9.5.1.20.1) or portTopNTable

(1.3.6.1.4.1.9.5.1.20.2) where portTopNControlIndex (1.3.6.1.4.1.9.5.1.20.1.1.1) has an

out-of-range value (the valid range is 1 through 5) occasionally causes a TLB exception. This

problem is ﬁxed in software release 5.2(1)CSX. (CSCdm13058)

• The trapDestOwner MIB object (1.3.6.1.2.1.16.19.13.1.5) is limited to 20 characters. This

problem is ﬁxed in software release 5.2(1)CSX (the new limit is 128 characters). (CSCdm17939)
