Purpose
Creates a named object that represents a set of policies that are to be
applied to a set of traffic classes. Policy-map names can contain
alphabetic, hyphen, or underscore characters, are case sensitive, and
can be up to 40 characters.
Associates a class map with the policy map and enters the configuration
mode for the specified system class.
The associated class map must be the same type as the policy
Note
map type.
Configures one or more qos-group values to match on for classification
of traffic into this class map. There is no default value.
Exits the system class configuration mode and enters policy-map mode.
Exits policy-map mode and enters global configuration mode.
Creates a named object that represents a class of traffic. Class-map
names can contain alphabetic, hyphen, or underscore characters, are
case sensitive, and can be up to 40 characters.
Configures the traffic class by matching packets based on a list of QoS
group values. Values can range from 0 to 5. QoS group 0 is equivalent
to class-default.
Exits class-map mode and enters global configuration mode.
Creates a named object that represents a set of policies that are to be
