Marking allows users to classify the traffic of the application to be executed according to the DSCP
value.
IP Precedence and DSCP Mapping Table
Default (000000)
DSCP offers three levels of service, Class Selector (CS), Assured Forwarding (AF) and Expedited
Forwarding (EF). AF1, AF2, AF3 and AF4 are four levels of assured forwarding services. Each AF has
three different packet loss priorities from high, medium, to low. Also, CS1-CS7 indicates the IP
precedence.
Rate Type: You can choose Limited or Prioritization.

Limited (Maximum): Specify a limited data rate for this policy. It also is the maximum rate for
this policy. When you choose Limited, type the Ratio proportion. As above FTP server
example, you may want to "throttle" the outgoing FTP speed to 20% of 256K and limit to it, you
may use this type.

Prioritization: Specify the rate type control for the rule to use. If you choose Prioritization for
the rule, you parameter Priority would be available, you can set the priority for this rule.
