Precautions ■The Switch 5500 supports VRRP, while the Switch 4500 does not.
■For the IP address owner, its priority in the VRRP group is always 255.
■When configuring VRRP interface tracking, you are recommended to configure
the uplink Trunk port to deny the VLAN that corresponds to the tracked
interface.
■When you set the priority decrease value of the master in a VRRP group, make
sure that the master has a lower priority than the backups after the decrease.
VRRP Port Tracking VRRP group port tracking function can track the link state of a physical port, and
decrease the priority of the switch when the physical port fails.
With this function enabled for a VRRP group, if the tracked physical port of the
master fails, the priority of the master decreases by the specified value
automatically, making a new election of the master in the group.
