PurposeCommand or Action
• class name—Name of the class to be configured or whose policy is to
be modified. The class name is used for both the class map and to
configure a policy for the class in the policy map.
• class-default—Specifies the default class so that you can configure or
modify its policy.
Enables color-aware traffic policing and creates the conform-color and
exceed-color class-maps used for color-aware traffic policing.
conform-color class-map-name
[exceed-color class-map-name]
Step 5
Example:
Router(config-pmap-c-police)#
conform-color c1 exceed-color c2
The conform-color class-map-name command creates the conform-color
class. The exceed-color class-map-name option creates the exceed-color class.
Configures traffic policing and specifies multiple actions applied to packets
marked as conforming to, exceeding, or violating a specific rate.
police [cir cir] [bc conform-burst] [pir
pir] [be peak-burst] [conform-action
Step 6
action [exceed-action action
Enters policy-map class police configuration mode. Use one line per action
that you want to specify:
[violate-action action]]] [conform-color
hipri-conform] [exceed-color
lipri-exceed]
• cir—Committed information rate. Indicates that the CIR will be used
for policing traffic.
Example:
Router(config-pmap-c)# police 10000
bc 1500
• conform-action—(Optional) Action to take on packets when the rate is
less than the conform burst.
• exceed-action—(Optional) Action to take on packets whose rate is within
the conform and conform plus exceed burst.
Example:
Router(config-pmap-c-police)#
conform-action set-qos-transmit 5
• violate-action—(Optional) Action to take on packets whose rate exceeds
the conform plus exceed burst. You must specify the exceed action before
you specify the violate action.
• conform-color—(Optional) Enables color-aware policing (on the policer
being configured) and assigns the class map to be used for conform color
determination. The hipri-conform keyword is the class map (previously
configured via the class-map command) to be used.
• exceed-color—(Optional) Enables color-aware policing (on the policer
being configured) and assigns the class map to be used for exceed color
determination. The lipri-exceed keyword is the class map (previously
configured via the class-map command) to be used.
Specifies a service policy as a QoS policy within a policy map (called a
hierarchical service policy).
service-policy policy-map-name
Example:
Router(config-pmap-c-police)#
service-policy child-policy
Step 7
• policy-map-name—Name of the predefined policy map to be used as a
QoS policy. The name can be a maximum of 40 alphanumeric characters.
