Using QoS Classifiers to Configure Quality of Service for Outbound Traffic
For example, suppose you wanted to assign this set of priorities:
Source-Port DSCP
A2 000111
B1-B3 000101
B4, C2 000010
1. Determine whether the DSCPs already have priority assignments, which
could indicate use by existing applications. This is not a problem as long
as the configured priorities are acceptable for all applications using the
same DSCP. (Refer to the "Notes on Changing a Priority Setting" on page
5-36. Also, a DSCP must have a priority configured before you can assign
any QoS classifiers to use it.)

2. Configure the priorities for the DSCPs you want to use.

The DSCPs for this
example have not yet
been assigned an
