[Sysname] vrrp ping-enable
vrrp vlan-interface vrid track
Syntax
vrrp vlan-interface vlan-id vrid virtual-router-id track [ reduced value-reduced ]
undo vrrp vlan-interface vlan-id vrid virtual-router-id track
View
Ethernet port view
Parameters
virtual-router-id: VRRP group ID, ranging from 1 to 255.
vlan-id: VLAN ID.
value-reduced: Value by which the priority of a switch is to decrease. This argument ranges from 1 to
255, and defaults to 10.
Description
Use the vrrp vlan-interface vrid track command to enable the port tracking function of a VRRP group
on a physical port.
Use the undo vrrp vlan-interface vrid track command to disable the port tracking function.
After the port tracking function of a VRRP group is enabled on a port, this function will track the link
status of the port. If a fault occurs on the port, the function decreases the priority of the switch where the
port resides by a specified value.
Usually, this function is used to track the status of the uplink port of the master in a VRRP group.
Thereby, when the uplink port of the master fails, the master’s priority will decrease by a specified value,
so as to trigger a new master election in the VRRP group.
z If an IP address owner exists in a VRRP group, the port tracking function configured on the IP
address owner cannot take effect.
z The port to be tracked can be in the VLAN whose VLAN interface has the VRRP group configured.
z Up to eight ports can be tracked simultaneously.
Examples
# Configure that the priority of the switch decreases by 50 if its Ethernet 1/0/1 port fails.
