Mapping DSCP Priority

The DSCP is six bits wide, allowing coding for up to 64 different

forwarding behaviors. The DSCP replaces the ToS bits, and it retains

backward compatibility with the three precedence bits so that non-DSCP

compliant, ToS-enabled devices, will not conflict with the DSCP mapping.

Based on network policies, different kinds of traffic can be marked for

different kinds of forwarding. The DSCP default values are defined in the

following table. Note that DSCP values that are not specified are mapped

to CoS value 0.

Fields and Attributes

•IP Precedence/DSCP Priority Status – Selects IP Precedence,

DSCP, or disables both priority services.

•DSCP Priority Table – Shows the DSCP Priority to CoS map.

•Class of Service Value – Maps a CoS value to the selected DSCP

Priority value. Note that “0” represents low priority and “7” represents

high priority.
