I am going to use VSS with a C3750 'Access' switch running 12.2(46)SE that supports Pagp+ for dual active detection. Regarding this topology, i have some questions:
1) Does my Etherchannel towards the C3750 stack need to be a Pagp Etherchannel ? Or can it be a fixed Etherchannel (mode on) ?
2) If the Etherchannel needs to be a Pagp Etherchannel before VSS can use the Pagp+ packets, does this imply that i can't use a cross-stack Etherchannel on the C3750, because cross-stack etherchannel did not support Pagp before ? Is it supported on 12.2(46)SE ?
