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.
Decrease the priority of a switch in a VRRP group when the result of the detected group is
unreachable.
Restore the priority of the switch in the VRRP group when the result of the detected group is
reachable.
If an IP address owner exists in a VRRP group, the auto detect function configured on the IP
address owner cannot take effect.
A detected group can be used to detect up to eight Layer 3 interfaces.
Currently, auto detect in VRRP is only supported in 5500-EI series switches.
