value: Specifies the priority for selecting DIS, ranging from 0 to 127, with the default as
64.
level-1: Specifies the priority for selecting level-1 DIS.
level-2: Specifies the priority for selecting level-2 DIS.
If neither level-1 nor level-2 is specified in this command, then the level-1 and level-2

also select DIS.
