Open and Resolved Caveats in Software Release 7.2(1)

Resolved Caveats in Software Release 7.2(2)

These caveats are resolved in software release 7.2(2):

• When the switch is running on one power supply, a faulty warning message is displayed in the output

of the show test command, even when the switch is configured for 1+1 redundancy.

Workaround: Ignore the warning. The switch needs only one power supply to operate. This

problem is resolved in software release 7.2(2). (CSCdx19680)

• The Idledetect feature does not work on 10/100 ports of a Catalyst 2980G-A switch. If you attempt

to configure Idledetect in the CLI, the switch ignores the configuration. This problem is resolved in

software release 8.3(1)GLX. (CSCec79821)

• Ports on a Catalyst 2980G-A switch can stop receiving packets when connected to some hosts or

ports with high ESD applied to them. This could happen in environments where cables are allowed

to charge up to a high voltage. The ports will not receive any good packets. The Rx good packet

count will not increase, and some error counters can increase when packets are received from

neighboring hosts and switches. The symptoms are only temporary and will not damage your

hardware. This problem is resolved in software releases greater than 7.2(1); however, it is disabled

by default.

To enable the fix, you must enable the idledetect feature, using the set port idledetect command.

This feature is available only on Catalyst 2980G-A 10/100 ports. This problem is resolved in

software release 7.2(2). (CSCdw37422)

• You might receive this faulty warning message:

%SYS-2-PS_INSUFFICIENT:Insufficient power supplies operating, this system requires 2

and only has 1

Workaround: Ignore the warning, the switch needs only one power supply to operate. This problem

is resolved in software release 7.2(2). (CSCdx22239)

• The Errdisable-timeout feature does not function properly on supervisor engine ports if the

supervisor engine status is faulty. This problem can be caused by any system failure that leads to a

faulty status on the supervisor engine, such as an unplugged power supply or bad fans. The problem,

if caused by a minor fault in the system, has been resolved; if the system registers a major fault (Red

console LED) the problem will still occur.

Workaround: Verify that your supervisor engine does not display a faulty status and physically

remove any unplugged power supplies from the chassis if you are using uplinks on your supervisor

engine. (CSCdw75253)
