DiffServ Wizard Overview
You can use the DiffServ Wizard to enable DiffServ on the switch by creating a traffic class,
adding the traffic class to a policy, and then adding the policy to the ports selected on DiffServ
Wizard screen. 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 below:
• VOIP. Sets match criteria to UDP protocol.
• HTTP. Sets match criteria to HTTP destination port.
• FTP. Sets match criteria to FTP destination port.
• Telnet. Sets match criteria to Telnet destination port.
• Every. Sets match criteria all traffic.
• Creates a Diffserv Policy and adds it to the DiffServ Class created.
• If Policing is set to YES, then DiffServ Policy style is set to Simple. Traffic that conforms
to the Class Match criteria is processed according to the Outbound Priority selection.
Outbound Priority configures the handling of conforming traffic as below:
• High. Sets policing action to markdscp ef.
• Med . Sets policing action to markdscp af31.
• Low. Sets policing action to send.
• If Policing is set to NO, then all traffic is marked as specified below:
• High. Sets policy mark ipdscp ef.
• Med. Sets policy mark ipdscp af31.
• Low. Sets policy mark ipdscp be.
• Each port selected is added to the policy created.
