The generic virtual MAC address is of the form 00:00:5e:00:01:\<VRID\>. For example, if you create a VRID with a value of 60 and bind it to an interface, the resulting virtual MAC address is 00:00:5e:00:01:3c, where 3c is the hex representation of the VRID. You can create 255 VRIDs with values from 1 to 255.
