Quality of Service (QoS): Managing Bandwidth More Effectively

Using QoS Classifiers To Configure QoS for Outbound Traffic

no qos device-priority < ip-address>

Deletes the specified IP address as a QoS classifier.

show qos device-priority

Displays a listing of all QoS Device Priority classifiers currently in the running-config file.

For example, suppose you wanted to assign these DSCP policies to the packets identified by the indicated IP addresses:

1.Determine whether the DSCPs already have priority assignments, which could indicate use by existing applications. This is not a problem if the configured priorities are acceptable for all applications using the same DSCP. (Refer to the “Note On Changing a Priority Setting” on page 6-61.Also, a DSCP must have a priority configured before you can assign any QoS classifiers to use it.)

The DSCPs for this example have not yet been assigned an 802.1p priority level.
