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 Figure 1-1, the Switch is connected to the router through GE 2/0/1; branch 1 and

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.

Configuration Roadmap

The configuration roadmap is as follows:

1. Create VLANs and configure interfaces so that branch 1 and branch 2 of the enterprise can

access the network through the Switch.
