1.1.13 vrrp vrid track

Syntax
vrrp vrid virtual-router-ID track vlan-interface interface-number [ reduced
value-reduced ]
undo vrrp vrid virtual-router-ID track [ vlan-interface interface-name ]
View
VLAN interface view
Parameter
virtual-router-ID: VRRP virtual router ID, ranging from 1 to 255.
vlan-interface interface-number: Interface which is to be tracked.
value-reduced: Reduced value of priority, ranging from 1 to 255; By default, the
reduced value of priority is 10.
Description
Use the vrrp vrid track command to configure the switch to track the interface.
Use the undo vrrp vrid track command to stop tracking the interface.
VRRP interface track expends the backup function, which thereby can be implemented
not only when the switch fails, but also when the state of a network interface is Down.
The user can use this command to track or stop tracking an interface or all the
interfaces. After the command is configured, the priority of the switch will be reduced, if
the state of the tracked interface goes Down. Accordingly, some other switch in the
virtual router will have the comparatively highest priority and become the new Master,
thereby implementing the backup function. The IP address owner does not allow the
configuration of interface tracking.
Each virtual router can track up to 8 interfaces.
Example
# Set to track vlan-interface1 on vlan-interface2, and lower the priority of virtual router 1
on vlan-interface2 by 50 when the state of vlan-interface1 goes Down.
[Quidway-vlan-interface2] vrrp vrid 1 track vlan-interface 1 reduced 50
