◆
First enter this command to designate a class map and enter the Class
Map configuration mode. Then use match commands to specify the
criteria for ingress traffic that will be classified under this class map.
◆
One or more class maps can be assigned to a policy map ( page 1411 ).
The policy map is then bound by a service policy to an interface
( page 1421 ). A service policy defines packet classification, service
tagging, and bandwidth policing. Once a policy map has been bound to
an interface, no additional class maps may be added to the policy map,
nor any changes made to the assigned class maps with the match or
set commands.
