41.2.9 Configuring Switch to Track a Specified Interface VRRP interface track function has expanded the backup function. Backup is provided
not only to the interface where the virtual router resides, but also to some other
malfunctioning switch interface. By implementing the following command you can track
some interface.
If the interface which is tracked is DOWN, the priority of the switch including the
interface will reduce automatically by the value specified by value-reduced, thus
resulting in comparatively higher priorities of other switches within the virtual router, one
of which will turn to Master switch so as to track this interface.
Perform the following configuration in VLAN interface view.
Table 41-9 Configure switch to track a specified interface
Operation Command
Configure the switch to track a specified
interface
vrrp vrid virtual-router-ID track
vlan-interface interface-num [ reduced
value-reduced ]
Stop tracking the specified interface undo vrrp vrid virtual-router-ID track
[ vlan-interface interface-num ]
By default, value-reduced is taken 10.
Note:
When the switch is an IP address owner, its interfaces cannot be tracked.
If the interface tracked is up again, the corresponding priority of the switch, including
the interface, will be restored automatically
You can only track up to eight interfaces in one virtual router.
