master-redundancy track-vrrp
Function
The master-redundancy track-vrrp command enables VRRP to track the status of an interface to negotiate the master AC and backup master AC roles.
The undo master-redundancy track-vrrp command disables VRRP from tracking the status of an interface to negotiate the master AC and backup master AC roles.
By default, VRRP is disabled from tracking the status of an interface to negotiate the master AC and backup master AC roles.

Usage Guidelines
Usage Scenario
During wireless configuration synchronization in VRRP HSB scenarios, the master AC and backup master AC roles are automatically elected through VRRP negotiation. The two ACs are bound to the same VRRP backup group, and VRRP tracks the status of the interface where it is configured. When the tracked interface becomes Down, the master AC and backup master AC exchange their roles. When the tracked interface recovers, the previous master AC and backup master AC roles are restored.
Prerequisites
A VRRP backup group has been created using the vrrp vrid virtual-ip command on the specified interface.
Precautions
The master-redundancy track-vrrp command is mutually exclusive with the master-controller and local-controller commands.
