XOS: ExtremeXOS version 15.3.3.5 v1533b5-patch1-2

One of our extreme x460/x450 stacks rebooted unexpectedly this morning (at 04:52 ) Logs suggests the following:

Mykhaylo,

You can share the outputs, once you have access to the switch. We will take a look at it and would share our feedback accordingly....

Thank guys. Just getting :

show ports stack-ports rxerrors no-refresh

show ports stack-ports txerrors no-refresh

[Vellachery__Sum]

Adding to it, please provide the output of "show slot".
Let's check if there are any Rx/Tx errors in the stacking ports. In case, if they are getting incremented we try to swap the stacking
cable

Mykhaylo,

The kernel oops which we have in the dump information has been occurred on Wed Apr 22 05:00:13 2015. Hence, this has nothing to do with the
current unexpected reboot.

As my colleague Aleixo suggested earlier. Please provide the output of
show stacking detail , will provide the info on configured stack mac -address
show switch from the Master node
show stacking
show ports stack-ports rxerrors no-refresh
show ports stack-ports txerrors no-refresh
