DiffServ Class Commands
Use the DiffServ class commands to define traffic classification. To classify traffic, you
specify Behavior Aggregate (BA), based on DSCP and Multi-Field (MF) classes of traffic
(name, match criteria)
This set of commands consists of class creation/deletion and matching, with the class match
commands specifying Layer 3, Layer 2, and general match criteria. The class match criteria
are also known as class rules, with a class definition consisting of one or more rules to identify
the traffic that belongs to the class.
NOTE: Once you create a class match criterion for a class, you cannot change or
delete the criterion. To change or delete a class match criterion, you must
delete and re-create the entire class.
The CLI command root is
class-map.
class-map

<class-map-name> is a case

class.
NOTE: The class-map-name 'default' is reserved and must not be used.

a packet to be considered a member of the class.
NOTE: The CLI mode is changed to Class-Map Config when this command is suc-
cessfully executed.
