This read-create integer, from 0 to 255 with a default of 100, sets a device's priority in determining which non-unready device becomes active within an RBRP group, with the device ID breaking ties between equal priorities. Admins raise this value on the device they want to preferentially become the active ring-protection node. For example, setting this to 200 on the preferred primary device, higher than other group members' default of 100, ensures it becomes active whenever it's in a ready state.
