We have a Matrix x4 for core switch and over 160 enterasys A,B,C stackable switches in our network.
I took off a 2nd Unit of a C2 switch, which is in redundant connection to the Matrix X4. After power off the Unit, the network crashes for 1 or 2 minutes.
I think, there is an error in the configuration of spanning tree or other things. But I dont know, how to fix it.
Is there anywhere a config to view, how it should be configured for the X4 and the A,B,C Switches?
