qos map phb-queue
This command determines the hardware output queues to use based on the
internal per-hop behavior value. Use the
no form to restore the default settings.
Syntax
qos map phb-queue queue-id from phb0 ... phb7
no map phb-queue phb0 ... phb7
phb - Per-hop behavior, or the priority used for this router hop. (Range: 0-7)
queue-id - The ID of the priority queue. (Range: 0-7, where 7 is the highest
priority queue)

Example
Console(config)#interface ethernet 1/5
Console(config-if)#qos map phb-queue 0 from 1 2 3
Console(config-if)#
qos map cos-dscp
This command maps CoS/CFI values in incoming packets to per-hop behavior and
drop precedence values for priority processing. Use the
no form to restore the
default settings.
Syntax
qos map cos-dscp phb drop-precedence from cos0 cfi0 ... cos7 cfi7
no qos map cos-dscp cos0 cfi0 ... cos7 cfi7
phb - Per-hop behavior, or the priority used for this router hop. (Range: 0-7)
drop-precedence - Drop precedence used for controlling traffic congestion.
(Range: 0 - Green, 3 - Yellow, 1 - Red)
cos - CoS value in ingress packets. (Range: 0-7)
