Syntax
vrrp vrid virtual-router-id track detect-group group-number [ reduced value-reduced ]
undo vrrp vrid virtual-router-id track detect-group group-number
View
VLAN interface view
Parameters
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.
Description
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.
