Release Notes for Catalyst5000 Family Software Release4.x

OL-2306-01

Open and Resolved Caveats in Software Release4.2(1)

• When you set the BOOT environment variable using SNMP, the trailing semicolon (;) is not

appended correctly, which can cause an error. This problem is resolved in software release 4.2(1).

(CSCdk36756)

• In some cases, after a module comes online, ports configured as a Fast or Gigabit EtherChannel

bundle (in on mode) do not form a channel.

Workaround: Reenter the set port channel mod_num/port_list on command. This problem is

resolved in software release 4.2(1). (CSCdk30075)

• In some cases, in a Catalyst 5000 family chassis with a Supervisor Engine III, if you move a Token

Ring port out of the default TrCRF VLAN (VLAN 1003) into a user-defined TrCRF and then move

the port back to the default TrCRF, connectivity might be lost on that port. This problem is resolved

in software release 4.2(1). (CSCdk34821)

• In some cases, during a switchover from the active to the standby supervisor engine, links on the

48-port, 4-segment 10BASE-T Telco Ethernet module (WS-X5020) and the 24-port, 3-segment

100BASE-TX RJ-45 Fast Ethernet module (WS-X5223) go down momentarily and come back up.

This problem is resolved in software release 4.2(1). (CSCdk27991)

• In some cases, when you switch over from the active to the standby supervisor engine, an exception

error occurs. In most cases, the supervisor engine resets and comes online properly. This problem

is resolved in software release 4.2(1). (CSCdk30533)

• In some cases, when you set an Ethernet port for dynamic VLAN membership and then you disable

the port using the set port disable command, the link goes down and comes back up continuously.

This problem is resolved in software release 4.2(1). (CSCdk30112)

• In certain situations, when you configure dynamic VLAN membership on an Ethernet port

configured as a SPAN source, the port does not get assigned to a VLAN properly and stays in

“inactive” mode. This problem is resolved in software release 4.2(1). (CSCdk30164)

• In some situations, an EtherChannel port might toggle up and down continuously. This problem is

resolved in software release 4.2(1). (CSCdk21348)

• When the SNMP agent on the Catalyst 5000 family switch receives a GET-REQUEST that uses an

invalid (out-of-range) vlanIndex instance to query a MIB object in the vlanTable, a bus exception

error is generated. This problem is resolved in software release 4.2(1). (CSCdk20786)

• In some cases, when you attempt to modify the VTP domain name (managementDomainName

object) through SNMP, the VTP domain name is not modified. This problem is resolved in software

release 4.2(1). (CSCdk30055)

• In some cases, the VTP configuration revision number (“Config Revision” in the show vtp domain

command output) is incorrectly reset to 1 when certain VTP parameters are changed through SNMP.

This problem is resolved in software release 4.2(1). (CSCdk25222)

• If an EtherChannel-capable port in off mode belongs to a VLAN that is used as a SPAN source, and

you move the port to a different VLAN without disabling SPAN first, SPAN continues to monitor

traffic on that port. This problem is resolved in software release 4.2(1). (CSCdk26638)

• In some circumstances, the Catalyst 5000 switch might drop some IGMP general queries, causing

the multicast router to not learn some IGMP reports.

Workaround: Enable CGMP on the multicast router. This problem is resolved in software release

4.2(1). (CSCdk37792)
