Configuring Quality of Service

Remember that if you want to establish the queue to an interface for which
you have already configure a map using the QoS wizard, you must enter the
name of that map. You can find this name in the Modify/Delete a QoS Map
section. (See, for example, Figure 14-38 on page 14-52.)

You will move to the QoS Map Setup for "<name>" window. Select the
criteria for the queue in the Match Packets section:
a.
To place RTP packets for certain applications in a queue, select IP
RTP. Then specify the range for the protocol ports by entering values
in the Start Port and End Port fields. By default, the map only matches
even ports. To match all ports, click the Enable Even and Odd Ports
box. Figure 14-40 shows a map that matches traffic to even ports from
16,384 to 32,767— typical destination ports for real-time protocols.
b. To place packets in a queue according to their DiffServ value, select
DSCP and enter a value between 0 and 63.

c.
To select packets according to their IP precedence value, select
Precedence and enter a value between 0 and 7.
d. If the router has any access control lists (ACLs) in its system, you can
choose one of these lists from the List pull-down menu. All packets
selected by the list will be placed in the low latency queue.
