Integer value that uniquely identifies the VMAC address. The generic VMACaddress is in the form of 00:00:5e:00:01:. For example, if you add a VRID with a value of 60 and bind it to an interface, the resulting VMAC address is 00:00:5e:00:01:3c, where 3c is the hexadecimal representation of 60.
This is mandatory parameter.
Minimum value = 1.
Maximum value = 255.

In an active-active mode configuration, make a backup VIP address the master if its priority becomes higher than that of a master VIP address bound to this VMAC address. If you disable pre-emption while a backup VIP address is the master, the backup VIP address remains master until the original master VIP's priority becomes higher than that of the current master.
Default value = ENABLED.
Possible Values : ENABLED, DISABLED.
