6.20.2 Class Commands

The 'class' command set is used in DiffServ to define:
Traffic Classification specifies Behavior Aggregate (BA) based on DSCP, and Multi- Field (MF)
classes of traffic (name, match criteria)
Service Levels specifies 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.
6.20.2.1 class-map
This command defines a new DiffServ class of type match-all, match-any or match-access-group.
Syntax
class-map [ match-all ] <class-map-name> [{ipv4 | ipv6}]
<class-map-name> is a case sensitive alphanumeric string from 1 to 31 characters uniquely identifying
the class.
When used without any match condition, this command enters the class-map mode. The
<class-map-name> is the name of an existing DiffServ class.
The class name 'default' is reserved and is not allowed here. 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.
The optional keywords [{ipv4 | ipv6}] specify the Layer 3 protocol for this class. If not
specified, this parameter defaults to 'ipv4'. This maintains backward compatibility for
configurations defined on systems before IPv6 match items were supported.
The CLI mode is changed to Class-Map Config or Ipv6-Class-Map Config when this
command is successfully executed depending on the [{ipv4 | ipv6}] keyword specified.
