Command Mode
Class Map Configuration
Command Usage
◆ First enter the class-map command to designate a class map and enter the
Class Map configuration mode. Then use match commands to specify the fields
within ingress packets that must match to qualify for this class map.
◆ If an ingress packet matches an ACL specified by this command, any deny rules
included in the ACL will be ignored.
◆ If match criteria includes an IP ACL or IP priority rule, then a VLAN rule cannot
be included in the same class map.
◆ If match criteria includes a MAC ACL or VLAN rule, then neither an IP ACL nor IP
priority rule can be included in the same class map.
◆ Up to 16 match entries can be included in a class map.
Example
This example creates a class map called “rd-class#1,” and sets it to match packets
marked for DSCP service value 3.
Console(config)#class-map rd-class#1 match-any
Console(config-cmap)#match ip dscp 3
Console(config-cmap)#
