Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers to Configure Quality of Service for Outbound Traffic
For example, suppose you wanted to assign this set of priorities:
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.)
Figure 5-13. Display the Current Configuration in the DSCP Policy Table
2. Configure the priorities for the DSCPs you want to use.
Figure 5-14. Assign Priorities to the Selected DSCPs
Source-Port DSCP Priority
A2 000111 7
B1-B3 000101 5
B4, C2 000010 1
The DSCPs for this
example have not yet
been assigned an
802.1p priority level.
