MATCH
32-5
Command Usage
• First enter the class-map command to designate a class map and
enter the Class Map configuration mode. Then use the match
command to specify the fields within ingress packets that must match
to qualify for this class map.
• Only one match command can be entered per class map.
• The class map uses the Access Control List filtering engine, so you
must also set an ACL mask to enable filtering for the criteria specified
in the
match command. See “mask (IP ACL)” on page 23-9 and
“mask (MAC ACL)” on page 23-21 for information on configuring an
appropriate ACL mask.
Example
This example creates a class map called “rd_class#1,” and sets it to match
packets marked for DSCP service value 3:
This example creates a class map call “rd_class#2,” and sets it to match
packets marked for IP Precedence service value 5:
This example creates a class map call “rd_class#3,” and sets it to match
packets marked for VLAN 1:
Console(config)#class-map rd_class#1_ match-any
Console(config-cmap)#match ip dscp 3
Console(config-cmap)#exit
Console(config)#access-list ip mask-precedence in
Console(config-ip-mask-acl)#mask any any dscp

Console(config)#class-map rd_class#2 match-any
Console(config-cmap)#match ip precedence 5
Console(config-cmap)#exit
Console(config)#access-list ip mask-precedence in
Console(config-ip-mask-acl)#mask any any precedence
Console(config-ip-mask-acl)#
Console(config)#class-map rd_class#3 match-any
Console(config-cmap)#match vlan 1
Console(config-cmap)#exit
