Diffserv; Class Commands - Planet WGSW-24000 User Manual

▫ i.e., ACL rules copied as class match criteria at time of class creation, with class type
'any'
▫ implicit ACL 'deny all' rule also copied
▫ no nesting of class type 'acl'
Regarding nested classes, referred to here as class references, a given class definition can contain at
most one reference to another class, which can be combined with other match criteria. The referenced
class is truly a reference and not a copy, since additions to a referenced class affect all classes that
reference it. Changes to any class definition currently referenced by any other class must result in valid
class definitions for all derived classes otherwise the change is rejected. A class reference may be
removed from a class definition.
The user can display summary and detailed information for classes, policies and services. All
configuration information is accessible via the CLI, Web, and SNMP user interfaces.

9.4 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
twolevel 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.
