Nexus VPC autorecovery.

Сообщение АлексейCCIE » 22 мар 2017 17:01

Hello guys!

If the vPC primary switch goes down, the vPC secondary switch stops receiving Keepalive messages on the vPC Peer Keepalive link. After three consecutive Keepalive message timeouts, the vPC secondary switch changes its role to be the vPC primary switch and brings up its vPC member ports.

In Cisco NX-OS Release 5.0(2)N2(1), if you enable the auto-recovery feature and if the vPC primary switch goes down, the vPC secondary switch does not receive messages on the vPC peer keepalive link. Then, after three consecutive keepalive timeouts, the vPC secondary switch changes its role to primary and brings up the vPC member ports.

In both cases (with and without autorecovery) the switch starts using the VPC links after 3 consecutive keep alive are missing. I am trying to figure out what the feature changes?
Have any of you had to figure that out?

I am sorry for writing in english, i just don't have russian keyboard handy.
