Reason switch in switch stack rebooted
One switch in a switch stack rebooted.
What command can I use to find out why?
This is an IOS based switch.
It was not the master that rebooted
The other switches have been up for some time but one of them rebooted last night.

I did a show clock on all three switches and the time is synchronized.
Looks like the switch removed from stack and then the vtp domain changed from the console?
Would that have to be local with a console cable?
