1.6 Configuration Examples

This section provides several configuration examples of class-based QoS.
1.6.1 Example for Configuring Priority Mapping Based on Simple
Traffic Classification
After priority mapping based on simple traffic classification is configured, the S7700 maps
802.1p priorities of packets to different CoS to provide differentiated services.
Networking Requirements
As shown in
branch 2 of the enterprise access the network through the Switch and router. Branch 1 and branch
2 of the enterprise belong to VLANs 100 and 200. Branch 1 requires better QoS guarantee;
therefore, the priority of data packets from branch 1 is mapped to 4 and the priority of data
packets from branch 2 is mapped to 2. By doing this, Switch provides differentiated services.
