Chapter 7 Configuring vPCs
Configuration Examples for vPCs
switch(config)# feature vPC
switch(config)# feature lacp
Step 2 (Optional) Configure one of the interfaces that you want to be peer link in dedicated mode.
switch(config)# interface ethernet 7/1, ethernet 7/3, ethernet 7/5. ethernet 7/7
switch(config-if)# shutdown
switch(config-if)# exit
switch(config)# interface ethernet 7/1
switch(config-if)# rate-mode dedicated
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)#
Step 3 (Optional) Configure the second, redundant interface that you want to be peer link in dedicated mode.
switch(config)# interface ethernet 7/2, ethernet 7/4, ethernet 7/6. ethernet 7/8
switch(config-if)# shutdown
switch(config-if)# exit
switch(config)# interface ethernet 7/2
switch(config-if)# rate-mode dedicated
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)#
Step 4 Configure the two interfaces (for redundancy) that you want to be in the peer link to be an active Layer
2 LACP port channel.
switch(config)# interface ethernet 7/1-2
switch(config-if)# switchport
switch(config-if)# switchport mode trunk
switch(config-if)# switchport trunk allowed vlan 1-50
switch(config-if)# switchport trunk native vlan 20
switch(config-if)# channel-group 20 mode active
switch(config-if)# exit
Step 5 Create and enable the VLANs.
switch(config)# vlan 1-50
switch(config-vlan)# no shutdown
switch(config-vlan)# exit
Step 6 Create a separate VRF for the vPC peer-keepalive link and add a Layer 3 interface to that VRF.
switch(config)# vrf context pkal
switch(config-vrf)# exit
switch(config)# interface ethernet 8/1
switch(config-if)# vrf member pkal
switch(config-if)# ip address 172.23.145.218/24
switch(config-if)# no shutdown
switch(config-if)# exit
Step 7 Create the vPC domain and add the vPC peer-keepalive link.
switch(config)# vpc domain 1
switch(config-vpc-domain)# peer-keepalive destination 172.23.145.217 source 172.23.145.218
vrf pkal
switch(config-vpc-domain)# exit
Step 8 Configure the vPC peer link.
switch(config)# interface port-channel 20
switch(config-if)# switchport mode trunk
