If you are familiar with the Cisco IOS CLI, be aware that the Cisco NX-OS commands for this feature
Note
might differ from the Cisco IOS commands that you would use.

Enabling the VRRP Feature

You must globally enable the VRRP feature before you can configure and enable any VRRP groups.
To enable the VRRP feature, use the following command in global configuration mode:
Command
feature vrrp
Example:
switch(config)# feature vrrp
To disable the VRRP feature in a VDC and remove all associated configuration, use the following
command in global configuration mode:
Command
no feature vrrp
Example:
switch(config)# no feature vrrp
OL-20002-02
You must configure an IP address for the interface that you configure VRRP on and enable that
interface before VRRP becomes active.
Cisco NX-OS removes all layer 3 configuration on an interface when you change the interface VRF
membership, port channel membership, or when you change the port mode to layer 2.
When you configure VRRP to track a Layer 2 interface, you must shut down the Layer 2 interface
and reenable the interface to update the VRRP priority to reflect the state of the Layer 2 interface.
