Mapping DSCP or CoS Values to an Egress Queue and to a Threshold ID

You can prioritize traffic by placing packets with particular DSCPs or costs of service into certain queues and
adjusting the queue thresholds so that packets with lower priorities are dropped.
Purpose
To return to the default WTD threshold percentages, use the no mls qos
Note
queue-set output qset-id threshold [queue-id] global configuration
command.
Specifies the port of the outbound traffic, and enter interface configuration mode.
Maps the port to a queue-set.
For qset-id, enter the ID of the queue-set specified in Step 2. The range is 1 to 2.
The default is 1.
Returns to privileged EXEC mode.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
To return to the default setting, use the no mls qos queue-set output qset-id buffers
global configuration command. To return to the default WTD threshold percentages,
use the no mls qos queue-set output qset-id threshold [queue-id] global
configuration command.
