Local vpc is down forwarding via vpc peer link vpc domain id.

What is vpc peer link what happens when it go down. Peer link not configured vpc keep alive status. If the vpc primary switch goes down the vpc secondary switch stops receiving keepalive messages on the vpc peer keepalive link. Vpc domain ids possible cause the vpc domain ids of two switches do not match.

When connectivity is restored the secondary stays primary and the configured primary becomes operationally secondary. The rest of the network had no idea that a failure occurred and there was no reconvergence necessary from a control plane perspective on any of the switches. Shuts down the svi associated to the vpc vlan.

When connectivity to a vpc peer is lost the default is to prevent any change in configuration. The keepalive link is used as a secondary test mechanism to confirm the vpc peer is live in case the peer link goes down. In the event the peer keepalive link fails it will not have a negative effect on the operation of the vpc which will continue forwarding traffic.

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. Local vpc is down forwarding via vpc peer link vpc domain id. I vpc member ports interface vlan s on the secondary goes into shutdown state after peer link is down.

Peer is alive configuration consistency status. Switch1 show vpc brief legend. Failed configuration consistency reason.

When vpc peer link fails down and vpc peer keepalive link is still up the vpc secondary peer device performs the following operations. Vpc systems behavior when a vpc peer link goes down. Switch1 show vpc brief legend.
