Priority Mapping Configuration
This chapter provides priority mapping configuration method, configuration examples, and common configuration errors.
- Priority Mapping
Priority mapping maps QoS priorities in packets to internal priorities (also called local priority, which is used by the device to differentiate CoS values of packets) to ensure QoS in the differentiated services (DiffServ) model based on internal priorities. - Priority Mapping Features Supported by the Device
This section describes priority mapping features supported by the device. - Configuring Priority Mapping on the S2700SI, S2700EI, and S2710SI
After priority mapping is configured, the Switch determines the queues that received packets enter and output priorities of the received packets based on packet priorities or the default 802.1p priority of the interface. By doing this, the Switch provides differentiated services. - Configuring Priority Mapping on the S2700-52P-EI, S2700-52P-PWR-EI, S3700SI, and S3700EI
After priority mapping is configured, the Switch determines the queues that received packets enter and output priorities of the received packets based on packet priorities or the default 802.1p priority of the interface. By doing this, the Switch provides differentiated services. - Configuration Examples
This section provides a priority mapping configuration example, including networking requirements, configuration notes, and configuration roadmap.
