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

hey, i ran this up in the lab, the FEX itself runs dual active detection without the need for PAGP.
see below info:
switch#show fex dual-active
FEX dual-active detection enabled: Yes
Channel Group 101 (FEX 101)
Splitbrain detection capable: Yes
switch 1 member port state:
Te1/5/2 - Interface Up. state: bound
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)
Splitbrain detection capable: Yes
switch 1 member port state:
Te1/5/4 - Interface Up. state: bound
switch 2 member port state:
Te2/5/4 - Interface Up. state: bound
switch#show switch virtual dual-active summary
Pagp dual-active detection enabled: Yes
Fast-hello dual-active detection enabled: Yes
FEX dual-active detection enabled: Yes
No interfaces excluded from shutdown in recovery mode
In dual-active recovery mode: No
