*1: When the value other than the range is specified to output priority, the setting becomes invalid.
*2: When QoS queue attribute of output interface is minimum bandwidth guarantee (kbit/s), flow control
is processed as follows:
• Queuing priority 1, 2: Flow control is processed by queuing priority 2.
• Queuing priority 3, 4: Flow control is processed by queuing priority 4.

This parameter makes valid the flow control function replaced
by TOS or DS field of Diff-serv. Sets the number of bits
replacing TOS or DS field of Diff-serv. The upper 6 bits of the
TOS or DS field of Diff-serv field are replaced. The lower 2 bits
are ignored even if this parameter is set. When this parameter
is set,
-priority_class
be set.
