7000 Series L3 Managed Switch Reference Manual for Software v2.0
9-2 CLI Commands: Differentiated Services
The following class restrictions are imposed by the 7000 Series L3 Managed Switch Software
DiffServ design:
• nested class support limited to:
– 'any' within 'any'
– 'all' within 'all'
– no nested 'not' conditions
– no nested 'acl' class types
– each class contains at most one referenced class
• hierarchical service policies not supported in a class definition
• access list matched by reference only, and must be sole criterion in a class
– 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.
General Commands
The following characteristics are configurable for the platform as a whole.
config diffserv adminmode
This command sets the DiffServ operational mode to active or inactive. The value for the
administrative mode is either enable or disable. The default value is disable. While disabled, the
DiffServ configuration is retained and can be changed, but it is not activated.
Format config diffserv adminmode <enable/disable>
