DES-7200 Configuration Guide Chapter 2 QoS Configuration
2-9
Command Description
DES-7200(config)# [no] class-map
class-map-name
Create and enter into the class map configuration
mode, where class-map-name is the name of the
class map to be created.
The no option will delete an existing class map
DES-7200(config-cmap)# [no] match
access-group {acl-num |
acl-name }
Set the matching ACL, where acl-name is the
name of the created ACL,
acl-num is the ID of the created ACL; the no option
delete that match.
For example, the following steps creates a class-map named class1, which is
associated with a ACL:acl_1. This class-map will classify all TCP messages with port
80.
DES-7200(config)# ip access-list extended acl_1
DES-7200(config-ext-nacl)# permit tcp any any eq 80
DES-7200(config-ext-nacl)# exit
DES-7200(config)# class-map class1
DES-7200(config-cmap)# match access-group acl_1
DES-7200(config-cmap)# end
