VSS with C3750 Pagp+ detection

Unanswered Question
Oct 31st, 2008

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 ?

I have this problem too.

If you want intelligence in the cross-stack etherchannel, I recommend using LACP in lieu of PAgP.
