# On VLAN-interface 2, configure to track VLAN-interface 1 and configure the priority of the master of 

VRRP group 1 (on VLAN-interface 2) to decrease by 50 when VLAN-interface 1 goes down.

VLAN interface view 

virtual-router-id: Virtual VRRP group ID, ranging from 1 to 255. 

group-number: Detected group number, ranging from 1 to 25. 

value-reduced: Value by which the priority decreases. This argument ranges from 1 to 255 and defaults 

to 10. 

Use the vrrp vrid track detect-group command to enable the auto detect function when employing 

VRRP. 

Use the undo vrrp vrid track detect-group command to disable the auto detect implementation in 

VRRP.  

The auto detect result of the detected group can control the priority of a switch in a VRRP group. In this 

way, the automatic switching between the master and the backup is implemented.  

z 

Decrease the priority of a switch in a VRRP group when the result of the detected group is 

unreachable. 

z 

Restore the priority of the switch in the VRRP group when the result of the detected group is 

reachable. 

 

z 

If an IP address owner exists in a VRRP group, the auto detect function configured on the IP 

address owner cannot take effect. 

z 

A detected group can be used to detect up to eight Layer 3 interfaces. 

z 

Currently, auto detect in VRRP is only supported in 5500-EI series switches.
