Thank Mark Malone for the information. Appreciate it.

The switch is up even it keeps on showing this alarm.

you will need to change the software version to fix it or just leave it as its cosmetic if upgrading is not an option , if its flooding your syslog use logging discriminator to drop it

Again I thank you. we are going to upgrade the switch to the latest software version

(c2960x-universalk9-mz.152-2.E6)... Appreciate a lot.

I tried now Release 15.2(2)E6 and 15.2(4)E4. No success. Problem doesn't disappear.

Seems we have to wait till there is a fix for the following software bug: CSCve04418

From our environment I have seen the following:

  • Cat2960XR with bootldr 15.0(2r)Ex1 are affected
  • Cat2960XR with bootldr 15.2(3r)E1 not affected

Unfortunately no way to force bootldr upgrade.

good to know. I am affected by this bug too.

We are facing the same issue with Catalyst WS-C2960XR-24PS-I. The affected switches are running 15.2(2)E5.

  • According to Bug CSCuv53498 issue should be solved with 15.2(2)E4.
  • According to Bug CSCve04418 this issue happens also on 15.2(2)E4.

In any case we actually shouldn't have the issue anymore with 15.2(2)E5 :-(.

Any experience from others from which release this issue is solved? Next try for us would be 15.2(2)E6.
