Queue	0	1	2	3

Priority	1,2	0,3	4,5	6.7

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 1 and 2 to priority queue 0, value 3 to queue 1, values 4 and 5 to queue 2, and values 6 and 7 to queue 3:

Console(config)#interface ethernet 1/1

Console(config-if)#queue cos-map 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)#exit

Console#show queue cos-map ethernet 1/1

Information of Eth 1/1
