Command	Function
queue cos-map	Syntax:
This command assigns	queue cos-map queue_id [cos1 ... cosn]

Use the no form set the	separated list of numbers. The CoS value is a number from 0 to 7, where 7 is
	the highest priority.

	queues, with Weighted Round Robin queuing for each port. Eight separate traffic
	classes are defined in IEEE 802.1p. The default priority levels are assigned
	according to recommendations in the IEEE 802.1p standard as shown below:
	Command Mode: Interface Configuration (Ethernet, Port Channel)
	Command Usage: CoS values assigned at the ingress port are also used at the
	egress port.
	This command sets the CoS priority for all interfaces.
	Example: The following example shows how to map CoS values 0, 1 and 2 to
	egress queue 0, value 3 to egress queue 1, values 4 and 5 to egress queue 2,
	and values 6 and 7 to egress queue 3:
	Console(config)#interface ethernet 1/1
	Console(config-if)#queue cos-map 0 0 1 2
	Console(config-if)#queue cos-map 1 3
	Console(config-if)#queue cos-map 2 4 5
	Console(config-if)#queue cos-map 3 6 7
	Console(config-if)#end
	Console#show queue cos-map ethernet 1/1

	CoS Value	: 0 1 2 3 4 5 6 7
	Priority Queue: 0 0 0 1 2 2 3 3
