•
Packets are filtered and processed based on defined criteria. The filtering criteria is
defined by a class. The processing is defined by a policy's attributes. Policy attributes
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 and LAGs 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 for VoIP traffic to the UDP protocol.
-
-
HTTP: Sets the match criteria for HTTP traffic to the HTTP destination port.
-
FTP: Sets match criteria for FTP traffic to the FTP destination port.
-
Telnet: Sets the match criteria for Telnet traffic to the Telnet destination port.
-
Every: Sets the match criteria for all traffic.
•
Sets a committed rate for the selected traffic type.
•
Creates a Diffserv policy and adds it to the DiffServ class.
•
Optionally, enables policing and sets the Diffserv policy as a simple policy.
When policing is enabled, traffic that conforms to the class match criteria is processed
according to the outbound priority selection, which handles conforming traffic as
follows:
-
High: Maps the traffic priority to DiffServ class Expedited Forwarding (EF).
-
Medium: Maps the traffic priority to DiffServ class Assured Forwarding (AF31).
-
Low: Maps the traffic priority to DiffServ class Best Effort (BE).
