Integer value that uniquely identifies the VMAC address. The generic VMACaddressis 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.
