Default None. DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Command Mode Policy-map Class Configuration Mode. Command Default Level Level: 12. Usage Guideline Use the police command to drop the packet or mark the packet with different quality of service (QoS) values based on conformance level of the packet. Use the police KBPS command to create a single rate policer. Use the police cir command to create a two rate policer. There are two kinds of single rate policers (1) a single rate two color policer and (2) a single rate three color policer. If the violate action is specified in the police KBPS command, then the policer is three colors. If not specified, the policer is two colors. As a packet arrives at a port, the packet will be initialized with a color. If the receive port trusts DSCP then the initial color of the packet is mapped from the incoming DSCP based on the DSCP to color map. If the receipt port trusts CoS then the initial color is mapped from the incoming CoS based on the CoS to color map. A single rate two color policer can only work in color-blind mode. Both single rate three color policers and two rate three color policers can work in color aware mode. In color-blind mode, the final color of the packet is determined by the policer metering result alone. In color-aware mode, the final color of the packet is determined by the initial color of the packet and the policer metering result. In this case the policer may further downgrade the initial color. After the policer metering action will be based on the final color. Conform action will be taken on green color packets, exceed-action will be taken on yellow color packets, and violate action will be taken on red color packets. When specifying actions, you cannot specify contradictory actions such as violate-action transmit and exceedaction drop. The actions configured by the set command for a traffic class will be applied to all the packets belonging to the traffic class. Example This example shows how to define a traffic class and associate the policy with the match criteria for the traffic class in a policy map. The service-policy command is then used to attach this service policy to the interface. In this particular example, traffic policing is configured with an average rate of 8 kilobits per second and a normal burst size of 1 kilobyte for all ingress packets at Ethernet 1/0/1.

Use the no form of this command to delete the name aggregate policer from a class policy. 1248
