56 CHAPTER 6: USING TRAFFIC PRIORITIZATION packet attributes on which to classify incoming traffic, Differentiated Services Code Point (DSCP) and IEEE 802.1D. 2 Identify Service Levels You must then identify the level of service each classifier should receive. Note that DSCP service levels will be set somewhere else in the network and not in the Switch 4200 Series. Note also that 802.1D service levels are fixed and cannot be altered. 3 Create Profiles The next step is to create a profile, which associates classifiers with service levels. 4 Apply Qos profile After a QoS profile has been created, it can be assigned to the Port(s). When the profile is assigned to the port(s), the QoS configuration defined in the profile will immediately become active.

Identify Service Levels
You must then identify the level of service each
classifier should receive. Note that DSCP service levels will be set
somewhere else in the network and not in the Switch 4200 Series. Note
also that 802.1D service levels are fixed and cannot be altered.

Create Profiles
The next step is to create a profile, which associates
classifiers with service levels.
4
Apply Qos profile
After a QoS profile has been created, it can be
assigned to the Port(s). When the profile is assigned to the port(s), the
QoS configuration defined in the profile will immediately become active.
