What Is Vpc Keepalive

The only traffic on this link is a message that indicates that the originating switch is operating and running vpc.

What is vpc keepalive. The peer keepalive link sends periodic keepalive messages between vpc peer devices. It is a special link for carrying l2 traffic between the vpc peer switches when there is a link failure. Monitoring is performed to ensure the switches are both operational and running vpc.

Normally it should get little use. Vpc keepalive keepalive is a physical link between both peer switches primary and secondary in vpc triangle. No data or synchronization traffic moves over the vpc peer keepalive link.

Vpc peer keepalive link the peer keepalive link provides a layer 3 communications path that is used as a secondary test in order to determine whether the remote peer is operating properly. In particular it helps the vpc switch to determine whether the peer link itself has failed or whether the vpc peer is down. Before the peer link will come up you also have to set up vpc keepalives to detect dual active peers when the vpc peer link is down.

The vpc peer keepalive link can be a management interface or switched virtual interface svi. Information about vpc operations a vpc allows links that are physically connected to two different cisco nexus 5000 series switches to appear as a single port channel to a third switch. Vpc peer keepalive link connects both vpc peer switches and carries monitoring traffic to from each peer switch.
