This section will cover how to configure virtual port channels (vPC) on a Nexus switch. I will be using a real Nexus 5010, but this can be done on any Nexus switch.

• vPC peers require (in order):
  1. Same domain number, limit of one per switch
  2. A peer link
  3. A keepalive link
  4. One or more vPC member ports

1. Enable NX-OS features
   1. Nexus(config)# feature vpc
   2. Nexus(config)# feature lacp
2. Configure domain number on each switch
   1. Nexus(config)# vpc domain 1
   2. Nexus(config-vpc-doamin)# peer-keepalive destination 192.168.1.185 (management VRF on other switch)
3. Configure port channel interfaces
   1. Nexus(config)# int e 1/17-18
   2. Nexus(config-if)# channel-group 1 mode active
   3. Nexus(config)# int po 1
   4. Nexus(config-if)# switchport
   5. Nexus(config-if)# switchport mode trunk
   6. Nexus(config-if)# vpc peer-link
4. Repeat on other switch
5. Verification commands
   1. show port-channel summary
   2. show vpc peer
