Description: Indicates the information of vlan policy as follows: Each octet within this value specifies a set of eight priorities. When the policy type is 8021p, the first octet specifying 8021p priority 0 through 7; When the policy type is dscp, the first octet specifying dscp priority 0 through 7, the second octet specifying priority 8 through 15, etc; When the policy type is eth-type, the most significant bit of the first octet specifying EtherType PPPOE. Within each octet, the most significant bit represents the lowest numbered priority, and the least significant bit represents the highest numbered priority. Thus, each priority is represented by a single bit within the value of this object. If that bit has a value of '1' then that priority is included in the set of priorities; the priority is not included if its bit has a value of '0'.
