4506E (SUP7-E) VSS to 3750X stack MEC and dual active
Hi, I am implementing VSS on a pair of 4506E switches with SUP7-E cards running 03.04.00.SG, they will be running MEC to access switches which are 3750 stacks. I want to prevent dual active scenario on the 4506, the options I believe I have are:
ePAgP - cant use this as 3750's do not support cross chassis etherchannel which we use.
I dont think that the last 2 options are supported on 4506E (sup7-e) chassis, can anyone confirm this ?
If as I believe they are not supported , how can i address the dual active scenario ????
The requirements for completing a MultiChassis EtherChannel is a neighbor switch. A MultiChassis EtherChannel is an EtherChannel with ports that terminate on both chassis of the VSS. Enhanced PAgP , Uses PAgP messaging over the MEC links in order to communicate between the two chassis through a neighbor switch. The Neighbor switch must be able to understand ePAgP.
