13.2 QoS Configuration Task List
1． Configure class map.
Set up a classification rule according to ACL, CoS, VLAN ID, IPv4 Precedent, DSCP, IPV6 FL to classify
the data stream. Different classes of data streams will be processed with different policies.
2． Configure a policy map.
After data steam classification, a policy map can be created to associate with the class map created
earlier and enter class mode. Then different policies (such as bandwidth limit, priority degrading assigning
new DSCP value) can be applied to different data streams. You can also define a policy set that can be
use in a policy map by several classes.
