Switching

I'm having issues with a Catalyst 3850 switch. It was a member of a stack of 3 switches, but I removed it from the stack because of strange flapping of ports and stack ports. Now that it is no longer a part of the stack, the stack is stable. This lea...

I would like to know about FEX communication with the parent Nexus switch in a bit more detail.  I know the FEX is assigned an IP from 127.0.0.0/8 segment... but how is this actually used?  Is communication with the FEX itself encapsulated in the VN ...

I'm at a loss to explain this one.  We just lost power to one of the switches in our Catalyst 3750 stack (of course it had to be the master) and another took over as master.  From this stack, we have a two port etherchannel to a stack of Brocade VDX ...
