Release Notes for Catalyst5000 Family Software Release4.x

OL-2306-01

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

• In a chassis with redundant Supervisor Engine III modules with NFFCs and the 24-port

10/100 BASE-TX Fast Ethernet module (WS-X5225R), you must have an uplink module installed

in the supervisor engine in slot2. Without an uplink module in the supervisor engine in slot2, the

synchronization between the active and standby supervisor engines might fail. (CSCdk41377)

• When you download a new software image to a Catalyst 5000 family switch with redundant

Supervisor Engine III modules and the BOOT environment variable on the standby supervisor

engine is too long (about 512bytes), the system synchronizes the software images but fails to

synchronize the BOOT variable.

Workaround: Clear all or part of the BOOT variable on the standby supervisor engine.

(CSCdk41232)

Note CSCdk41232 has not been seen in later releases.

• When upgrading to software release 4.2(1) from a previous release, if you download the software

image file and then hot insert a second supervisor engine before you reset the system, the standby

supervisor engine does not synchronize with the primary. (CSCdk31881)

• Duplicate packets might be seen on an RSM VLAN interface after you move the interface from one

DMA channel to the other using the dma-channel interface configuration command.

Workaround: Enter the microcode reload global configuration command after entering or

removing a dma-channel command on RSM interfaces. (CSCdk45657)

Resolved Caveats in Software Release4.2(1)

Note For a description of open caveats in software release 4.2(1), see the “Open Caveats in Software

Release4.2(1)” section on page67.

This section describes the caveats resolved in software release 4.2(1):

• If you have redundant Fast EtherChannel links and redundant Gigabit Ethernet links, and UplinkFast

is enabled, Fast EtherChannel might be incorrectly chosen as the primary path.

Workaround: Manually adjust the port costs. This problem is resolved in software release4.2(1).

(CSCdk02273, CSCdk10855)

• A port on the three-port Gigabit Ethernet module (WS-X5403) might not establish a link with some

Gigabit Ethernet network interface cards (NICs) if autonegotiation is enabled on the port. When

autonegotiation is disabled on the port, a link is established normally. This problem is resolved in

software release4.2(1). (CSCdk29940)

• A Catalyst 5500 switch might reload continuously when the SNMP historyControlInterval.x is set

to a very small number, such as two seconds.

Workaround: In crease the historyControlInterval.x to a larger number, such as 30 seconds, or

disable RMON on the switch by entering the set snmp rmon disable command. This problem is

resolved in software release4.2(1). (CSCdk23780)

• In a Catalyst 5000 family chassis with redundant Supervisor Engine III modules, if the standby

supervisor engine does not have an uplink module installed and you remove the standby supervisor,

install an uplink module, and reinsert the module with the switch still running, the uplink ports on

the standby supervisor engine are not activated (they are disabled). This problem is resolved in

software release 4.2(1). (CSCdk28678)
