Configuring IP Precedence Classification

You can classify traffic based on the precedence value in the type of service (ToS) byte field of the IP header.
The precedence values are listed in the following:
Purpose
Enters global configuration mode.
Creates or accesses the class map named class-name and
enters class-map mode. The class-map name can contain
alphabetic, hyphen, or underscore characters, and can be
up to 40 characters.
Configures the traffic class by matching packets based on
dscp-values. The standard DSCP values are shown in the
following table.
Use the not keyword to match on values that do not match
the specified range.
Exits global class-map queuing mode and enters global
configuration mode.
(Optional) Saves the running configuration to the startup
configuration.
