Command History
Usage Guidelines Before using the class command, you must use the policy-map global configuration command to
identify the policy map and to enter policy-map configuration mode. After specifying a policy map, you
can configure a policy for new classes or modify a policy for any existing classes in that policy map.
You attach the policy map to a port by using the service-policy interface configuration command.
After entering the class command, you enter policy-map class configuration mode, and these
configuration commands are available:
• exit: exits policy-map class configuration mode and returns to policy-map configuration mode.
• no: returns a command to its default setting.
• police: defines a policer or aggregate policer for the classified traffic. The policer specifies the
bandwidth limitations and the action to take when the limits are exceeded. For more information,
see the
police and police aggregate policy-map class commands.
• set: specifies a value to be assigned to the classified traffic. For more information, see the set
command.
• trust: defines a trust state for traffic classified with the class or the class-map command. For more
information, see the
trust command.
To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode,
use the end command.
The class command performs the same function as the class-map global configuration command. Use
the class command when a new classification, which is not shared with any other ports, is needed. Use
the class-map command when the map is shared among many ports.
class-map-name Name of the class map.
