Diffserv Class Configuration
Use the Diffserv Class Configuration page to define the criteria to associate with a DiffServ class. As
packets are received or transmitted, these DiffServ classes are used to classify and prioritize packets.
Each class can contain multiple match criteria.
After you select the class to configure from the Class menu, use the buttons to perform the following
tasks:
•
To define criteria for matching packets within a class, click Add Match Criteria . Once you add a
match criteria entry to a class, you cannot edit or remove the entry. However, you can add more
match criteria entries to a class until the maximum number of entries has been reached for the class.
This button is not available if the class type is
ACL because the match criteria are defined by the ACL
rules.
•
To remove the associated reference class from the selected class, click Remove Reference Class.
Note that unless the reference class is the last entry in the list of match criteria, the Reference Class
match type remains in the list as a placeholder, but the associated value is N/A, and the previously
referenced class is removed.
