VSS SWITCH 2 RELOADED WITH NO APPARENT REASON

Hi,

I configured two catalyst 6509 switches into a VSS cluster. After 5 weeks the secondary chassis reloaded itself with no apparent reason, I have tried to search some information to explain this but I could not find anything.

For some reason VSL interfaces went down and triggered VSL failure, the chassis 2 reloaded and the VSS reinitialized. I have attached  -show logging, show switch virtual and show switch virtual redundancy commands.

Actually the VSS is working fine but I would like to know about this behavior, does anyone have any ideas ¿?.

Regards,

-Sergio

Hi Sergio,

Keep an eye on the power supplies for the backup 6500.  The log shows that the power supply mode changes and the fan running on high speed.

I also noticed you are running SXH and not SXI.  Do a comparison of the 2 image and you see that SXI gives you a lot more features then SXH.

So if you ever have to upgrade SXI3 is pretty solid.

Hi

I found why the VSS standby chassis initiated a stateful switchover (SSO), here the link..
