Beginning in privileged EXEC mode, follow these steps to create a nonhierarchical policy map:
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 class-map [match-all | match-any]
class-map-name Create a class map, and enter class-map configuration mode.
By default, no class maps are defined.
•(Optional) Use the match-all keyword to perform a logical-AND
of all matching statements under this class map. All match cri teria
in the class map must be matched.
•(Optional) Use the match-any keyword to perform a logical-OR of
all matching statements under this class map. One or more match
criteria must be matched.
•For class-map-name, specify the name of the class map.
If neither the match-all or match-any keyword is specified, the default
is match-all.
Note Because only one match command per class map is supported,
the match-all and match-any keywords function the same. See
the “Creating Named Standard and Extended ACLs” section on
page 34-15 for limitations when using the match-all and the
match-any keywords.
Step3 policy-map policy-map-name Create a policy map by entering the policy map na me, an d en te r
policy-map configuration mode.
By default, no policy maps are defined.
The default behavior of a policy map is to set the DSCP to 0 if the
packet is an IP packet and to set the CoS to 0 if the packet i s tagged. N o
policing is performed.
Step4 class class-map-name Define a traffic classification, and enter policy-map class configuration
mode.
By default, no policy map class-maps are defined.
If a traffic class has already been defined by using the class-map glob al
configuration command, specify its name for class-map-name in this
command.
