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.
