Syntax

View
VLAN interface view
Parameters
virtual-router-id: Virtual router ID ranging from 1 to 255.
group-number: Detected group number ranging from 1 to 25.
value-reduced: Value by which the priority is to be reduced. This argument ranges from 1 to 255 and
defaults to 10.
Description
Use the vrrp vrid track detect-group command to specify an auto detected group for a VRRP group.
Use the undo vrrp vrid track detect-group command to cancel the configuration.
You can enable Auto Detect on the master switch in a VRRP group, use the Auto Detect function to
detect the links from the master to other networks, and use the detection results
(reachable/unreachable) to control the priority of the master, so as to realize the automatic
master-backup switchover:
The master keeps as master when the detected group is reachable.
The priority of the master decreases and thus becomes a backup when the detected group is
unreachable.
Currently, auto detect in VRRP is only supported in S3600-EI series Ethernet switches.
Examples
# Specify to decrease the priority of the master switch in VRRP group 1 by 20 when the detected group
10 is unreachable.
