6.2.5.2.2. Configuring DiffServ Class Configuration Page
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, is this field 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.
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, is this field a selector field. After class creation this becomes a
