police

Command History

Usage Guidelines You can enter a single conform-action, exceed-action, or violate-action as part of the command string

following the police command. You can also press Enter after the police command to enter policy-map

class police configuration mode, where you can enter multiple actions. In policy-map class police

configuration mode, you must enter an action to take.

The switch also supports marking multiple QoS parameters for the same class and simultaneously

configuring conform-action, exceed-action, and violate-action marking.

The switch supports single-rate policing with a 2-color marker, or a 2-rate policer with a 3-color marker.

Mapped packets can be sent without modification, dropped, or marked to options specified by the set

command. Note that traffic rates are configured in bits per second and burst size is entered in bytes.

You can configure policing for any number of classes on any one of the three levels of the policy-map

hierarchy. If you configure marking on one level, you can configure policing without marking (transmit,

drop) on another level.

The ME 3600X switch supports 2000 policers. The number of policers supported on the ME 3800X

switch is either 8000 or 16000, depending on the switch license.

An output policy map should match only the modified values of the out-of-profile traffic and not the

original values.

When you define the policer and press Enter, you enter policy-map class police configuration mode, in

which you can configure multiple policing actions. These commands are available:

• conform-action

• exceed-action

• violate-action

• exit: exits from QoS policy-map class police configuration mode. If you do not want to set multiple

actions, you can enter exit without entering any other policy-map class police commands.

• no: negates or sets the default values of a command.

You can verify the configuration by entering the show policy-map privileged EXEC command.

Examples This example shows how to create a traffic classification with a CoS value of 4, create a policy map, and

attach it to an ingress port. The average traffic rate is limited to 10000000 b/s with a burst size of

10000 bytes:

Switch(config)# class-map video-class

Switch(config-cmap)# match cos 4

Switch(config-cmap)# exit

Switch(config)# policy-map video-policy

Switch(config-pmap)# class video-class

Switch(config-pmap-c)# police 10000000 10000

Switch(config-pmap-c)# exit

Switch(config-pmap)# exit

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# service-policy input video-policy

Switch(config-if)# exit
