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 list of CoS values. Values can range from 0 to 7. Use
the not keyword to match on values that do not match the
specified range.
Note When a Cisco Nexus Fabric Extender (FEX) is
connected and in use, data traffic should not be
marked with a CoS value of 7. CoS 7 is reserved
for control traffic transiting the Fabric Extender.
Exits global class-map queuing mode and enters global
configuration mode.
(Optional) Saves the running configuration to the startup
configuration.
