- vPC virtual port channel, let port's on 2 vPC peers look like they are from one switch, eliminating blocked ports on ethertrunk.
- Step1 enable features needed on switches.

- peer-gateway - only for dumb hosts that do not use arp for gw discovery, but incoming packet.
- pinning max-links 1
- Before the peer link will come up, you also have to set up VPC keepalives to detect dual active peers

- VPC Rule 101
- VPC peers are expected to forward a frame received on a member link out any other member link that needs to be used. Only if they cannot do so due to a link failure, is forwarding across the VPC peer link and then out a member link allowed, and even then, the cross-peer-link traffic can only go out the member link that is paired with the member link that is down.
- Restatement of VPC Rule 101
- To put it another way, VPC peers are expected to forward a frame received on a member link out any other member link that needs to be used. Only if they cannot do so due to a link failure, is forwarding across the VPC peer link and then out a member link allowed, and even then, the cross-peer-link traffic can only go out the member link that is paired with the member link that is down.
- With VPC, one should always put keepalives on a different link than the VPC peer link, since their purpose is to detect a situation with the peer still up but VPC peer link down. You just can't do that if they're running over the peer link. Instead, you can use the management port. Or, if you put a separate point-to-point routed link between the peers, in parallel with the VPC peer-link, you can use that for the keepalives.
- The L3 decision determines the outbound interface. If that outbound link is a VPC member link, the same forwarding rule is applied as for L2: the frame (packet) came in the peer-link, the member interface that is VPC-paired to the chosen outbound link is up, therefore drop the packet.
- Check fiber signal strength.
