You cannot configure VRRP on the management interface.
When VRRP is enabled, you should replicate the VRRP configuration across switches in your
network.
We recommend that you do not configure more than one first-hop redundancy protocol on the same
interface.
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.
