Figure 4-5-12 Diffserv Class Configuration
Selection Criteria
。 Class Selector - Along with an option to create a new class, this lists all the existing DiffServ class names, from
which one can be selected. The content of this screen varies based on the selection of this field. If an existing
class is selected then the screen will display the configured class. If '--create--' is selected, another screen appears
to facilitate creation of a new class. The default is the first class created. If no classes exist, the default is
'--create--'.
。 Class Type - This lists all the platform supported DiffServ class types from which one can be selected. Possible
options are 'all', 'any', or 'acl'. If 'acl' is (supported and) selected, then an access list (ACL) number is required
which is an integer specifying an existing ACL. Only when a new class is created, this field is a selector field. After
class creation this becomes a non-configurable field displaying the configured class type.
。 Class Match Selector - This lists all match criteria from which one can be selected to be added to a specified
class. The match criterion 'Every' denotes that every packet is considered to match the specified class and no
additional input information is needed. The content of this drop down list varies for a specified class based on the
selection of the match criterion 'Reference Class':
¾ If the specified class does not reference any other class, the 'Reference Class' match criterion is included in
the drop down match criteria list. A class reference can be established by selecting 'Reference Class' and
invoking the 'Add Match Criteria' button.
¾ If the specified class references another class, the 'Reference Class' match criterion is not included in the
drop down match criteria list. This prevents the user from trying to add yet another class reference, since a
specified class can reference at most one other class of the same type. Moreover, a 'Remove Class
Reference' button appears on the screen that can be invoked to remove the current class reference.
Configurable Data
。 Class Name - This is a case-sensitive alphanumeric string from 1 to 31 characters uniquely identifying a class.
Class name 'default' is reserved and must not be used.
Non-Configurable Data
。 Class Type - Displays type of the configured class as 'all', 'any', or 'acl'. Only when a new class is created, this
field is a selector field. After class creation this becomes a non-configurable field.
。 Match Criteria - Displays the configured match criteria for the specified class.
。 Values - Displays the values of the configured match criteria.
。 Excluded - Displays the inclusion or exclusion of the configured match criteria. When a match criterion is
