Purpose
Creates or accesses the class map named class-name and

contain alphabetic, hyphen, or underscore characters, and
can be up to 40 characters.
Configures the traffic class by matching packets based on
the specified protocol. Use the not keyword to match on
protocols that do not match the protocol specified.
Exits global class-map queuing mode and enters global
configuration mode.
(Optional) Saves the running configuration to the startup
configuration.
