Ahigher priority means that the switch is more likely to become the master. Note thatpriority 0 is reserved for special use and 255 for the IP address owner.z If the switch is the IP address owner, its priority is always 255. Therefore, it will bethe master so long as it is functioning normally.Examples# Set the priority of standby group 1 on interface VLAN-interface 2 to 150. system-view[Sysname] interface vlan-interface 2[Sysname-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.1[Sysname-Vlan-interface2] vrrp vrid 1 priority 150
