Figure : Differentiated Services Class Config
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. Options:
All
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 'Any' denotes that all packets are 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':
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.
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 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.
