[{-maxDescription:priority_classSpecifies8-maxmaximumpriorityoutputclasspriority16-.max_priorityclass32}]

￿	-max_priority_class 8: The maximum output priority is 8.
	-max_priority_class 16: The maximum output priority is 16.
	-max_priority_class 32: The maximum output priority is .
Default:	When using this list in input side: 8
	When using this list in output side: The number of queue of
	output interface
	(When this parameter is omitted, maximum class of output
	priority is dynamically changed at the change of queue count
	of output interface. Omitting of this parameter is
	recommended.)

[-priorityDescription:class<NoThis.>][parameter-discard_classenables<Noflow.>]control through output priority class and discard class queuing mechanisms. The value set for <No.> in this parameter represents priority.

For purposes of output precedence, the - _

	parameter indicates output priority. However, when used in
	respect to minimum bandwidth guarantee (the bandwidth
	queue mode), it functions as the queue number.
	Note that when this parameter is active, the parameters
	-replace_tosand -tos_mapcannot be specified.
