Can anyone tell me that this error means?  I have two Extreme EPS-500 switches in a stack, I lost all network connectivity this morning and had to console in via serial to reboot the stack... this is the only error I could see in the logs....

Thanks

Sounds like a stacking issue to me, check or replace the cables if you have spares. What version XOS do they run?

Hi, thanks for your reply - don't have any spare cables but will investigate!

Version is 12.2.1.1 v1221b1

What do you get from the 'sh stacking' command?

That looks fine. If you 'sh port 2:1' does it display details as you would expect?

Yep, nothing out of the ordinary at all.

Just to clarify, as it is a 2 switches stacked - for a continuity point of view if I spread a device, such a server, across both switches, if one goes down it should still be able to survive with the second?

I think the way they have it here is as a "100 port switch" and have not split any devices to take into account resilency.

Thanks

You can split devices over switches if your using port grouping / sharing. The NIC's on the servers would need to support it also. You will need the latest version of XOS to do that however. This is odd, your stack looks fine and if the master can see information from the secondary slot ports then communication is good. Can devices on the switch ping each other, even on the same slot?

Everything is back to normal now - after the swiches were rebooted via a console session. (in future a bit more troubleshooting needs to be done at the time).

I was thinking of bridging the NICs on the server and splitting them across the stack...

I have a nasty taste in my mouth when I can't find a route cause!

Thanks for the help, I'll close the question as all seems to be working fine now.  I've logged a SA with Extreme just to be safe.
