Open and Resolved Caveats in Software Release 4.3(1)

Open Caveats in Software Release4.3(1)

Note For a description of caveats resolved in software release 4.3(1), see the “Resolved Caveats in

Software Release4.3(1)” section on page59.

This section describes open caveats in software release4.3(1).

Caution If your switch contains an ATM module running Token Ring LANE software, you must install Token

Ring LANE software release 70.1(4) or later before you install Catalyst5000 family supervisor

engine software release4.3(1a) on the supervisor engine. If you fail to install the new Token Ring

LANE software first, the ATM module might not come online correctly.

Caution There are known problems that exist in Token Ring LANE software releases 70.1(5) and earlier and

Catalyst5000 family supervisor engine software release 4.3(1) that affect spanning tree

convergence. These problems can cause an instability in a redundant Token Ring LANE

configuration that can result in an extended network outage or a split network. These conditions

increase when there is heavy traffic in the network. We strongly recommend that you do not

configure a redundant Token Ring LANE configuration with supervisor engine software release

4.3(1) and Token Ring LANE software releases prior to 70.1(5). For additional information, see the

release notes your Token Ring LANE software release.

• 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).

• 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)

• If two IEEE 802.1Q-capable peers are negotiating a trunk when a spanning tree loop or prolonged

line-rate traffic exists, a port inconsistency error might occur, causing an excessive number of

syslog messages to be sent to the console. (CSCdk29882)

• On a Catalyst 5000 family switch with redundant supervisor engines, if you enable both port

security and VMPS, you might see a “Minor hardware problem” error on the standby supervisor

engine after a reset.

Workaround: Reset the standby supervisor engine. (CSCdk59755)
