DSCP

Differentiated services monitoring (DiffServ) is designed to monitor the network traffic usage of differentiated services code point (DSCP) values.

To monitor DSCP groups, you must configure at least one aggregation profile and one or more aggregation groups associated with each profile. For more information on configuring an aggregation profile, see DSCP Groups, page 2-64.

You can monitor the DSCP information by going to Analyze > Traffic > DSCP Traffic Analysis. You will see the DSCP group information as shown in Figure 3-5.
