4500X VSS - secondary unit crash

Carlos Rocha
Level 1
Level 1

Hi all,

We have a pair of 4500X switches running in VSS mode. They are running Version 03.04.06.SG RELEASE SOFTWARE (fc1).

Suddenly, the secondary unit crashed and started rebooting in a loop, as showed below. I would like to know if there is a way to recover this secondary unit.  Any help is welcome!

 

 Program Done!

Thanks Mark for the post!  But unfortunately, it didn't work.  I've tried the whole procedure, but the result is always the same.  I've even tried to load a newer software release, through the USB, but with no success... Below is the result:

Did you try removing the switch from VSS and bring it up as standalone?

Hi,

there is still the "Ask the Expert - VSS" right here in the LAN, Switching and Routing section:

https://supportforums.cisco.com/discussion/12599066/ask-expert-implementing-and-troubleshooting-virtual-switching-system-vss-cisco

... a perfect opportunity to discuss such issues!

You may also want to ask there for a software recommendation. We had a lot of trouble with 3.4 and 3.5 and running an 3.6 (Engineering Special if i recall correctly) at the moment.

HTH

Thanks Rolf for the post!  I was about to post on the "Ask the Expert - VSS", but now, I don't think it's really related to VSS.  I'm trying to reboot the switch with factory configuration, but it doesn't load the IOS until the end...

About the software release, I tried to use the latest release this afternoon, but the result was the same.  The switch freezes when trying to load the IOS and after some time reboots again, in a loop...
