vPC Autorecovery

[cwhite0013]

Hello,

I have a questions about the auto-recovery. The 240 second time seems like quite a long time to wait to bring the ports back online however the scenarios that I am reading sound like it would be pretty rare. My question is about the one scenario where the peer-link fails and THEN the primary device fails. I understand that the auto-recovery would take place then however what would happen if you just pull the power on the primary device? Will you still have to wait the 240 seconds for the interfaces on the secondary device or will the secondary device see that the peer-link and peer keep-alive link have failed at the same time and continue forwarding traffic?

Hi,

The auto-recovery is scenario is only used when both primary and secondary switch go down.

If you pull the power on the primary device the 240 seconds wait does not apply and the second switch will take over right a way.  You may lose one or 2 pings but the fail over is very fast.
