vPC Configuration on Nexus Switches [Step by Step]
Note
A symmetric configuration will be configured on both Nexus-1 and Nexus-2.
Contents
Step-1: Enable vPC and LACP features:
NX-1(config)# feature vpc
NX-1(config)# feature lacp
Step-2: Configure vPC domain:
NX-1(config)#vpc domain 1
Step-3: Peer KeepAlive Configuration
Both management interfaces and SVIs can be used for peer keepalive links. The management interface and VRF management instance are the defaults and recommended.
configure terminal
interface mgmt 0
ip address 192.168.10.1 255.255.255.0
no shutdown
exit
vpc domain 1
peer-keepalive destination 192.168.10.2 source 192.168.10.1 vrf management
Verify KeepAlive is up via the command below:
show vpc peer-keepaliveStep-4: Configure vPC peer-link:
NX-1(config)# interface ethernet 1/10-11
NX-1(config-if-range)# description ## Peer-link ##
NX-1(config-if-range)# channel-group 10 mode active
NX-1(config)# interface port-channel 10
NX-1(config-if)# description ## Peer-link ##
NX-1(config-if)# switchport mode trunk
NX-1(config-if)# switchport trunk allowed vlan 1-100
NX-1(config-if)# vpc peer-linkVerify vPC status with the command below:
show vpc
Step-5: Configure vPC downlink Interfaces:
interface Ethernet1/1
description ## Connected to Downstream Device ##
switchport access vlan 50
channel-group 20
interface port-channel 20
switchport access vlan 50
vpc 20
