QoS Classifiers 575
■
You can define up to 100 flow classifiers and up to 16 nonflow
classifiers. Because the Multilayer Switching Module predefines
16 nonflow classifiers, you must delete one of the existing nonflow
classifiers (except the default classifier) before you can add your own
nonflow classifiers. See “Modifying and Removing Classifiers and
Controls” later in this chapter for information about changing or
deleting a classifier.
■
When you configure a classifier, the Multilayer Switching Module
prompts you for different information based on your choice of
defining a flow or nonflow classifier.
Using Predefined
Classifiers
Figure 66 shows a QoS classifier summary from the Administration
Console with the two predefined flow classifiers (FTP and Telnet) and
16 predefined nonflow classifiers, along with their associated controls.
(You can use your configuration tool to display summary and detail
information for your classifiers.)
The Multilayer Switching Module provides a default classifier (499), which
you cannot remove or modify
. To first modify one of the predefined
nonflow classifiers with controls, you must remove the control.
In Figure 66, U means unicast, M means multicast, and B means
broadcast. Also, the range 0 through 7 implies that a nonflow classifier
recognizes all IEEE 802.1p priority tags. (See Table 92.)
