1.2.9 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 1-9 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-number [ reduced value - reduced ]
Stop tracking the specified
interface undo vrrp vrid virtual - router - ID track [ vlan-interface
interface-number ]
By default, value - reduced is taken 10.
Note:
z
When the switch is an IP address owner, its interfaces cannot be tracked.
z
If the interface tracked is up again, the corresponding priority of the switch, including
the interface, will be restored automatically
z
You can only track up to eight interfaces in one virtual router.
