Thanks for the info - I don't think this will be applicable to our
setup, in that we have all FE Ints in Portchannels, then each client is
a Portchannel SubInterface - So on each 7206, we have 3 FE's all bound
together in one PortChannel - So all traffic comes in, and goes back out
over the 3 FE's.
