Figure 7. The Completed DSCP Policy Configuration for the Specified
UDP/TCP Port Applications
The switch will now apply the DSCP policies in figure
the specified UDP/TCP port applications. This means the switch will:
■
Overwrite the original DSCPs in the selected packets with the new DSCPs specified in the above
policies.
■
Assign the 802.1p priorities in the above policies to the selected packets.
Displaying the QoS Resources
When creating QoS classifiers using UDP or TCP and a layer 4 Application port number or port range,
the switch automatically assigns two QoS resources for each policy—one for traffic to the UDP/TCP
destination port and one for traffic to the UDP/TCP source port.
The show qos resources command displays the QoS resources used in addition to the ACL and IDM
resources used.
