Packet processing begins by testing the class match criteria for a packet. 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 Dif
fServ 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 Dif
fServ 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 traf
fic.
• Create a Dif
fserv policy and add it to the DiffServ class created.
• If policing is enabled (that is, it is set to
YES), 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.
• Med. Sets the policing action to markdscp af31.
• Low. Sets the policing action to send.
• If policing is disabled (that is, it is set to NO), all traf
fic is marked as follows:
• High. Sets the policy mark to ipdscp ef.
• Med. Sets the policy mark to ipdscp af31.
• Low. Sets the policy mark to ipdscp be.
• Each port selected is added to the policy created.
