DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide Default None. Command Mode Policy-map Class Configuration Mode. Command Default Level Level: 12. Usage Guideline As a packet arrives at a port, the packet will be initialized with a color. The receiving port either trusts DSCP or CoS. The initial color of the packet is mapped from the DSCP in the incoming packet if the receiving port trusts DSCP. The initial color of the packet is mapped from the CoS in the incoming packet if the receiving port trusts CoS. Both single rate three colors 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; The policer may further downgrade the initial color. After the policer metering and based on the final color, the 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 the actions, you cannot specify contradictory actions such as violate-action transmit and exceed-action drop. The actions configured by the set command for the traffic class will be applied to all the packets belonging to the traffic class. Example This example shows how two-rate traffic policing is configured on a class called police to limit traffic to an average committed rate of 500 kbps and a peak rate of 1 Mbps, and the policy map named policy1 is attached to Ethernet 1/0/3.

Use the no form of this command to delete a policy map. policy-map NAME no policy-map NAME 770
