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:

Source-Port

DSCP

Priority

A2

000111

7

B1-B3

000101

5

B4, C2

000010

1

 

 

 

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 “Note On Changing a Priority Setting” on page 15-54.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.

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

Priorities Configured in this step.
