Table 12. DSCP Remarking Options
Option
Description
Dscp remarking mode
Lets you select the DSCP remarking mode that the Gateway is to use. Choices are:
•
Map frame priority to AF code points = select this option for Quality of Service configurations that use
assured forwarding (AF) code points to mark packets. AF guarantees a certain amount of bandwidth to
an AF class and allows access to extra bandwidth, if available. (default)
•
Map frame priority to CS code points = select this option for Quality of Service configurations that use
class selector (CS) code points to mark packets. CS provides code points that can be used for
backward compatibility with IP Precedence. IP Precedence is a legacy technology that the Gateway
supports for backwards compatibility.
Request a remarking action when DSCP equals one of the following CPs
Expedited Forwarding
Code Point
Expedited forwarding provides a low-loss, low-latency, low-jitter, and assured bandwidth service.
Applications such as VoIP, video, and other time sensitive applications require a robust network treatment
like expedited forwarding. When checked, the Gateway requests a remarking action if DSCP equals an
expedited forwarding code point. By default, this option is not checked.
Assured Forwarding
Code Points
Assured forwarding defines a method by which packets can be given different forwarding assurances.
Traffic can be divided into different classes and then each class given a certain percentage of bandwidth.
For example, one class could have 50% of the available link bandwidth, another class could have 30%,
and another 20% of the bandwidth. When checked, the Gateway requests a remarking action if DSCP
equals an assured forwarding code point. By default, this option is not checked.
Class Selector Code
Points
Class Selector code points are code points that can be used for backward compatibility with IP Precedence
models. When checked, lets the Gateway request a remarking action if DSCP equals a class selector code
point. By default, this option is checked, but does not take effect until the OSPF Status changes to
ENABLE.
Zero
When checked, lets the Gateway request a remarking action if DSCP equals zero. By default, this option is
checked, but does not take effect until the OSPF Status changes to ENABLE.
Others
When checked, lets the Gateway request a remarking action if DSCP equals a non-zero value. By default,
this option is checked, but does not take effect until the OSPF Status changes to ENABLE.
