Procedure Step 1 Enable vPC and LACP. NX-5000-1# configure terminal NX-5000-1(config)# feature lacp NX-5000-1(config)# feature vpc Step 2 Create the vPC domain and add the vPC peer-keepalive link. NX-5000-1(config)# vpc domain 1 NX-5000-1(config-vpc-domain)# peer-keepalive destination 10.10.10.237 NX-5000-1(config-vpc-domain)# exit Step 3 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 20 mode active NX-5000-1(config-if-range)# exit NX-5000-1(config)# interface port-channel 20 NX-5000-1(config-if)# vpc peer-link NX-5000-1(config-if)# exit Step 4 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 OL-16597-01 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide 145
