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':
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.
