AV Line of Fully Managed Switches M4250 Series Main User Manual can be defined on a per-class instance basis, and it is these attributes that are applied when a match occurs. • The configuration process begins with defining one or more match criteria for a class. Then one or more classes are added to a policy. Policies are then added to interfaces. Packet processing begins by testing the match criteria for a packet. The All class type option specifies that each match criteria within a class must evaluate to true for a packet to match that class. The Any class type option specifies that at least one match criteria must evaluate to true for a packet to match that class. Classes are tested in the order in which they were added to the policy. A policy is applied to a packet when a class match within that policy is found. DiffServ wizard overview The DiffServ wizard enables DiffServ on the switch by creating a traffic class, adding the traffic class to a policy, and then adding the policy to the ports that you select. The DiffServ wizard does the following: • Creates a DiffServ class and defines match criteria used as a filter to determine if incoming traffic meets the requirements to be a member of the class. • Sets the DiffServ class match criteria based on traffic type selection as follows: - VOIP: Sets the match criteria to UDP protocol. - HTTP: Sets the match criteria to HTTP destination port. - FTP: Sets match criteria to FTP destination port. - Telnet: Sets the match criteria to Telnet destination port. - Every: Sets the match criteria for all traffic. • Create a Diffserv policy and add it to the DiffServ class created. • Marks traffic as follows: - Policing enabled: If policing is enabled, the DiffServ policy style is set to simple. Traffic that conforms to the class match criteria is processed according to the outbound priority selection. The outbound priority configures the handling of conforming traffic as follows: - High: Sets the policing action to markdscp ef. - Medium: Sets the policing action to markdscp af31. - Low: Sets the policing action to send.
