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

This section describes open and resolved caveats in supervisor engine software release 5.2(1)CSX.

Open Caveats in Software Release 5.2(1)CSX

This section describes open caveats in supervisor engine software release 5.2(1)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

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

(CSCdm01334)

• If the software image on the MSM is not bootable, contact Cisco’s Technical Assistance Center

(TAC) at 800 553-2447, 408 526-7209, or tac@cisco.com. This problem is ﬁxed in software

release 5.2(2)CSX. (CSCdm03564)

• If the switch is in VTP client mode, entry of a copy device:ﬁlename conﬁg command may

generate messages about nonexistent VLANs. Wait until the show vlan command displays the

VLANs and then enter the copy command again. This problem is ﬁxed in software release

5.3(1)CSX. (CSCdm07337)

• When the last port in a VLAN that is actively participating in GMRP gets removed, the switch

might experience a watchdog exception or a TLB exception. This problem is ﬁxed in software

release 5.2(2)CSX. (CSCdm11116)

• If protocol ﬁltering is conﬁgured for an EtherChannel before the channel forms, it works

correctly. If you conﬁgure protocol ﬁltering after the channel has formed, it may not work

correctly for transmitted trafﬁc. This problem is ﬁxed in software release 5.2(2)CSX.

(CSCdm16439)

• Do not conﬁgure anymodule so that the number of GVRP-enabled ports, including the individual

physical ports in GVRP-enabled EtherChannels, times the number of VLANs on the module,

exceeds 720. This problem is ﬁxed in software release 5.3(1)CSX. (CSCdm18614)

• On switches with more than 100 VLANs, after removing a module or entering a set module

power down command, wait at least 60 seconds before putting the module back into service,

either by reinserting it or by entering a set module power up command. This problem is ﬁxed

in software release 5.2(2)CSX. (CSCdm19125)

• The Multilayer Switch Module (MSM) is not supported as a SPAN source port. Conﬁguring the

MSM as a SPAN source port generates a “Failed to conﬁgure source port” message. If you

conﬁgure the MSM as a SPAN source port, all subsequent SPAN source port conﬁguration

commands for that SPAN session generate the same message until you remove the MSM from

the source port list with a set span disable mod_num/port_num command. This problem is ﬁxed

in software release 5.3(1)CSX. (CSCdm20365)
