I have a switch stack of two 3750s. Recently the master in the stack rebooted. I am trying to determine why. Unfortunately the switch is only configured to log to the internal bufer and this has been overwritten with more recent events. Is there any way to find out why the restart occured (it wasn't planned).

Hi Leonard,
Can you check the output of "sh version" it should show you reload reason. This output may give you some idea.

Hi Ankur
"sh version" tells you when the stack was reloaded and why which in our case was a power on a few weeks ago which I am aware of. The recent restart of the master switch is displayed at the bottom of the command output but it doesn't display a reason why.

Hi Gary,
Can you issue a command "sh tech" and see if you get any stack trace? Also is it possible for you to post the output of "sh version"?

Hi Gary,
With the outputs I cannot find anyting specific. Can you issue "sh tech" and then do you see any crash or stack trace?

Hi Ankur
I've looked through the "sh tech". I can't see anything related to a crash. But I'm not 100% sure what to look for though.

Is there a way of configuring the switch so that it dumps info in the future?
