I have a couple of 3750 stacks.
I am trunking them together (I am runnign BGP on each of them with seperate providers and AS numbers...)
I am trying to set up some redundancy int he trunks so should one of the 3750s fail, the trunk will remain up. I tried to set up a port channel group (L2 Ether Channel) across the two blades (one port on 3750 A and one on 3750 B), but that seems to be illegal.
Does anybody know how I can configure a L2 port channel across a 3750 stack? Or something similar that achieves redundancy?
