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 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.
