Cisco Systems N5KC5596TFA manual Configure the vPC peer link as a two port Etherchannel

Configuring Virtual Port Channels

Single Homed Fabric Extender vPC Configuration Example

Step 2 Enable SVI interfaces, create the VLAN and SVI to be used by the vPC peer-keepalive link.

NX-5000-1(config)#feature interface-vlan

NX-5000-1(config)# vlan 900

NX-5000-1(config-vlan)# int vlan 900

NX-5000-1(config-if)#ip address 10.10.10.236 255.255.255.0

NX-5000-1(config-if)# no shutdown

NX-5000-1(config-if)# exit

Step 3 Create the vPC domain and add the vPC peer-keepalive link in the default VRF.

NX-5000-1(config)# vpc domain 30

NX-5000-1(config-vpc-domain)#peer-keepalive destination 10.10.10.237 source 10.10.10.236

vrf default

NX-5000-1(config-vpc-domain)# exit

Note VLAN 900 must not be trunked across the vPC peer-link because it carries the vPC peer-keepalive messages. There must be an alternative path between switches NX-5000-1 and NX-5000-2 for the vPC peer-keepalive messages.

Step 4 Configure the vPC peer link as a two port Etherchannel.

NX-5000-1(config)#interface ethernet 1/1-2

NX-5000-1(config-if-range)# switchport mode trunk

NX-5000-1(config-if-range)#switchport trunk allowed vlan 20-50

NX-5000-1(config-if-range)#switchport trunk native vlan 20

NX-5000-1(config-if-range)# channel-group 30 mode active

NX-5000-1(config-if-range)# exit

NX-5000-1(config)#interface port-channel 30

NX-5000-1(config-if)# vpc peer-link

NX-5000-1(config-if)# exit

Step 5 Configure the Fabric Extender NX-2000-100.

NX-5000-1(config)# fex 100

NX-5000-1(config-fex)# pinning max-links 1

NX-5000-1(fex)# exit

Step 6 Configure the fabric EtherChannel links for the Fabric Extender NX-2000-100.

NX-5000-1(config)#interface ethernet 1/20-21

NX-5000-1(config-if)# channel-group 100

NX-5000-1(config-if)# exit

NX-5000-1(config)#interface port-channel 100

NX-5000-1(config-if)#switchport mode fex-fabric

NX-5000-1(config-if)# fex associate 100

NX-5000-1(config-if)# exit
