Within a policy map, the class (policy-map) command can be used to specify the name of the class whose
Usage Guidelines
policy you want to create or change. The policy map must be identified first.
To identify the policy map (and enter the required policy map configuration mode), use the policy-map
command before you use the class (policy-map) command. After you specify a policy map, you can configure
the policy for new classes or modify the policy for any existing classes in that policy map.
The class name that you specify in the policy map ties the characteristics for that class—that is, its policy—to
the class map and its match criteria, as configured using the class-map command.
The class-default keyword is used for configuring default classes. It is a reserved name and cannot be used
with user-defined classes. It is always added to the policy map (type qos) even if the class is not configured.
For example, the following configuration shows that the class has not been configured, but the running
configuration shows 'class class-default'.
RP/0/RP0/CPU0:router(config)# class-map p2
RP/0/RP0/CPU0:router(config-cmap)# match precedence 2
RP/0/RP0/CPU0:router(config-cmap)# end-class-map
RP/0/RP0/CPU0:router(config)# commit
RP/0/RP0/CPU0:router(config)# policy-map pm2
RP/0/RP0/CPU0:router(config-pmap)# class p2
RP/0/RP0/CPU0:router(config-pmap-c)# set precedence 3
RP/0/RP0/CPU0:router(config-pmap-c)# end-policy-map
RP/0/RP0/CPU0:router(config)# commit
RP/0/RP0/CPU0:router(config)# end
