Vrrp Vrid Authentication-Mode - 3Com 5500-EI PWR Reference Manual

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.
If an IP address owner exists in a VRRP group, the port tracking function configured on the IP
address owner cannot take effect.
The port to be tracked can be in the VLAN whose VLAN interface has the VRRP group configured.
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.
