6880-X VSS dual-active detection with Enhanced PAgP

Hello,

I plan to use Enhanced PAgP for dual-active detection for a VSS consisting of 6880-X.

 

Has anybody tested it?

What about the 6800IA switch - does it have a similar feature that can help the active switch in the VSS to find out if the former standby has become also active?

 

Thanks, kind regards,

Eduard Gheorghiu

      Te1/5/3    - Interface Up.      state: bound       
    switch 2 member port state:
      Te2/5/2    - Interface Up.      state: bound       
      Te2/5/3    - Interface Up.      state: bound       

Channel Group 102 (FEX 102)
