Here is my network.  The switch that was unplugged was 10.11.1.205.  All critical systems are attached to the 1st floor avaya.  Our contact center sits behind the 2nd floor avaya.

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.
