Cisco Nexus 5000 Series Nx-Os Layer 2 Switching Configuration Guide, Release 5.1(3)N1(1 - Cisco nexus 5000 series Configuration Manual

Enhanced vPC Example Configuration
SUMMARY STEPS
1. Enable the vPC and LACP features on each switch.
2. Create required VLANs on each switch.
3. Assign a vPC domain ID and configure the vPC peer-keepalive link on each switch.
4. Configure the vPC peer link on each switch.
5. Configure port channels from the first FEX to each switch.
6. Configure port channels from the second FEX to each switch.
7. Configure a host port channel on each FEX.
DETAILED STEPS
Step 1 Enable the vPC and LACP features on each switch.
Example:
switch-1(config)# feature vpc
switch-1(config)# feature lacp
switch-2(config)# feature vpc
switch-2(config)# feature lacp
Step 2 Create required VLANs on each switch.
Example:
switch-1(config)# vlan 10-20
switch-2(config)# vlan 10-20
Step 3 Assign a vPC domain ID and configure the vPC peer-keepalive link on each switch.
Example:
switch-1(config)# vpc domain 123
switch-1(config-vpc)# peer-keepalive destination 172.25.182.100
switch-2(config)# vpc domain 123
switch-2(config-vpc)# peer-keepalive destination 172.25.182.99
Note When you configure each switch, use the IP address of the peer switch as the peer-keepalive destination.
Step 4 Configure the vPC peer link on each switch.
Example:
switch-1(config)# interface eth1/1-2
switch-1(config-if)# channel-group 1 mode active
switch-1(config-if)# interface Po1
switch-1(config-if)# switchport mode trunk
switch-1(config-if)# switchport trunk allowed vlan 1, 10-20
switch-1(config-if)# vpc peer-link
switch-2(config)# interface eth1/1-2
switch-2(config-if)# channel-group 1 mode active
switch-2(config-if)# interface Po1
switch-2(config-if)# switchport mode trunk
switch-2(config-if)# switchport trunk allowed vlan 1, 10-20
