User’s Guide 569/1523
The following class restrictions are imposed by the LB8 Series L3 Switch DiffServ design:
nested class support limited to:
'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
that is, 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.
