Catalyst 2948G Gives Multiple Errors...

Greetings,

I have an issue with a 2948G switch. The unit generates the following errors (sample given bellow) and stops switching on all ports. A reset of the switch resolves the issue for a period a day or so, after which, then produces the given errors and the halt of all switching functions.

The unit is running the latest RMON and CAT/IOS.

I have searched Cisco’s TAC and Forums but noting the mirrors this. This baby FUBAR?

Errors:

Re: Catalyst 2948G Gives Multiple Errors...

From the looks of it, it appears you are running into the following bug

Follow the steps listed in the bug and if it matches, you'll need to open a TAC case and RMA a switch.

Re: Catalyst 2948G Gives Multiple Errors...

Is there a code fix for this because we ran into this not too long ago on a 2948 and we have seen this on Cat4000's also . Is this strictly a hardware issue ?

6.4(7) has enhancements to flag switches exhibiting this symptom

Fix would be to replace hardware
