1. Experimental topology:

Because of the limited conditions, two N5Ks are used for basic vPC experiments, and Peer Keepalive Link uses two Mgm0 interfaces of Nexus 5K.

Second, configuration steps:

1. Build vPC domain first, and define role priority, system priority and PKL under domain.

2. Then configure Port-channel as PL.

3. Configure vPC member ports and vPC.

4. Configure Port-channel of Catalyst4500X switch.

Peer-switch > for other SW, do you see the same MAC address?

This value needs to be different. The small one becomes Primary, the big one becomes Secondary, and if the same, the small MAC becomes Primary.

System-priority 2100 > this value needs to be configured to be consistent in the same domain.
