XOS 12.6.1.3 stack crashes after 1555 days uptime

[Matthew_Tedder]

We have two Extreme stacks that have shown the same behavior at 1555 days uptime:

Slave switch breaks out of stack and becomes 2nd master,
All ports on slave switch go dark. (they can be bounced to re-enable directly from switch 2)

Has anyone else experienced this? I just love uptime bugs.....

[Matthew_Tedder]

Sure, here you go - Ill paste both switches outputs for the X670s so you can see the difference now:

Edit - should've refreshed before posting. Thanks Matthew

That's an odd one, Matthew. I don't think we've seen it before.
12.6 is unsupported now but we can test and see if it's something that has been fixed in a later version. Can you give me some more information about your gear?

code:

show switch

and

code:

show slot

should be enough for now.

X460V-48T in stack 1 and X670V-48x in stack 2. Both are on XOS 12.6.1.3

Hi Matthew,

What type of switches are in the stack and what EXOS version are they running?
