4.3 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
.
4.3.1 class-map
This command defines a DiffServ class of type match-all. When used without any
match condition, this command enters the class-map mode. The
<class-map-name>
is
a case sensitive alphanumeric string from 1 to 31 characters uniquely identifying an
existing DiffServ class.
NOTE: The class-map-name 'default' is reserved and must not be used.
The class type of
match-all
indicates all of the individual match conditions must be
true for a packet to be considered a member of the class.
NOTE: The CLI mode is changed to Class-Map Config when this command is
successfully executed.
