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
policy-map class commands.
•
set
: specifies a value to be assigned to the classified traffic. For more information, see the
command.
•
trust
: defines a trust state for traffic classified with the
class
or the
class-map
command. For more
information, see the
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.
