Class Commands
The 'class' command set is used in DiffServ to define:
Traffic Classification Specify Behavior Aggregate (BA), based on DSCP, and Multi-
Field (MF) classes of traffic (name, match criteria)
Service Levels Specify the BA forwarding classes / service levels. Conceptually,
DiffServ is a two-level hierarchy of classes: 1. Service/PHB, 2.
Traffic Class
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
belonging to the class. Note that once a class match criterion is created for a class, it cannot be
changed or deleted - the entire class must be deleted and re-created.
The CLI command root is
class-map.
class-map
This command defines a new DiffServ class of type match-all, match-any or match-access-group.
The <classname> parameter is a case sensitive alphanumeric string from 1 to 31 characters
uniquely identifying the class (Note: the class name 'default' is reserved and must not be used
here).
When used without any match condition, this command enters the class-map mode. The
<classname> is the name of an existing DiffServ class (note: the class name 'default' is reserved
and is not allowed here)
