Open and Resolved Caveats in Software Release 4.4(1)

• In some cases, on a switch with both BackboneFast and UplinkFast enabled, the show spantree

mod_num/port_num command output shows that a port is in forwarding mode, but in reality the port

is in listening mode. As a result, all data traffic received on the port is discarded.

Workaround: Disable and reenable the affected port. This problem is resolved in software

release4.5(1). (CSCdm08504)

• If you disable a switching module, trunk ports configured on the module might not be removed from

the spanning tree, possibly resulting in spanning tree loops when the module is reenabled.

Workaround: Reset the module. This problem is resolved in software release4.5(1).

(CSCdm02421)

• In some cases, a Catalyst 5000 family switch with redundant supervisor engines might reset as a

result of the change from Daylight Saving Time to Standard Time. This problem only occurs if the

Daylight Saving Time adjustment is enabled (using the set summertime enable command) and the

switch has not been reset or power-cycled since the change to Standard Time. This problem is

resolved in software release 4.5(1). (CSCdk57762)

Open Caveats in Software Release4.4(1)

Note For a description of caveats resolved in software release4.4(1), see the “Resolved Caveats in

Software Release4.4(1)” section on page54.

This section describes open caveats in software release4.4(1).

• If you have multiple ATM fabric integration modules (WS-X5165) installed and you have more than

50 LECs configured on each module, a multiple-module software download to the modules can take

an excessively long time to complete. For this reason, we recommend that you download software

images one module at a time (by specifying the module number in the download command).

(CSCdk55355)

• On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved

to another, previously unused secured port on the same module, the host cannot connect to the

network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then

reenable port security on the first port (if desired). (CSCdk31747)

• On the Gigabit EtherChannel module (WS-X5410), when the native VLAN of a trunk port is cleared

and then the trunk port is set to off, the port is placed in the inactive state but the Link LED for the

port still shows green. The correct behavior is that the LED for the port should show orange.

(CSCdk31985)

• In some cases, if you change the VLAN assignment of ports in a Fast EtherChannel, some ports are

placed in the errdisable state and the channel is not renegotiated. The correct behavior is that the

channel is torn down and renegotiated. (CSCdk32807)
