Use the Class Configuration page to add a new DiffServ class name, or to rename or delete
an existing class. The page also allows you to define the criteria to associate with a DiffServ
class. As packets are received, these DiffServ classes are used to prioritize packets. You can
have multiple match criteria in a class. The logic is a Boolean logical-and for this criteria. After
creating a Class, click the class link to the Class page.

Class Configuration.

To configure a DiffServ class:

To create a new class, enter a class name, select the class type, and click ADD. This

field also lists all the existing DiffServ class names, from which one can be selected.

The switch supports only the Class Type value All, which means all the various match
criteria defined for the class should be satisfied for a packet match. All signifies the logical
AND of all the match criteria. 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.

To rename an existing class, select the check box next to the configured class, update the

name, and click APPLY.

To remove a class, click the check box beside the Class Name, then click DELETE.

Click REFRESH to refresh the page with the most current data from the switch.

Click CANCEL to cancel the configuration on the screen and reset the data on the screen to

the latest value of the switch. After creating a Class, click the class link to the Class page.
