[c-nsp] Possible spanning tree issue

[Michael Sprouffske]

I attached a new switch to the network and it took down our contact center that doesn't touch this switch nor does the phone system.  Is this spanning tree doing this?  I don't see anything in the logs that show a change in spanning tree.

I also had an employee unplug a switch by accident and it took down our contact center.  This switch is all by itself and does not directly touch the phone system nor is it in the path of the phone system.  I feel like this shouldn't have happened.  


Any help would be awesome.
