Classifying Traffic by Using Class Maps
You use the class-map global configuration command to name and to isolate a specific traffic flow (or class)
from all other traffic. The class map defines the criteria to use to match against a specific traffic flow to further
classify it. Match statements can include criteria such as an ACL, IP precedence values, or DSCP values. The
match criterion is defined with one match statement entered within the class-map configuration mode.
Note
You can also create class maps during policy map creation by using the class policy-map configuration
command.
SUMMARY STEPS
1. configure terminal
2. Use one of the following:
3. class-map [match-all | match-any] class-map-name
4. match {access-group acl-index-or-name | ip dscp dscp-list | ip precedence ip-precedence-list}
5. end
6. show class-map
7. copy running-config startup-config
