Configuring Layer 3 Packet Length Classification

You can classify Layer 3 traffic based on various packet lengths.
Note This feature is designed for IP packets only.
Purpose
Enters global configuration mode.
Creates or accesses the class map named class-name and then
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 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.
