1.7.1 Example for Configuring Priority Mapping Based on Simple
Traffic Classification on the S3700HI
After priority mapping based on simple traffic classification is configured, the S3700 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.

Data Preparation
To complete the configuration, you need the following data:

Create VLANs and configure interfaces so that Branch 1 and Branch 2 of the enterprise
can access the network through the Switch.
Create DiffServ domains and map 802.1p priorities to PHBs and colors.
Bind the DiffServ domain to inbound interfaces GE0/0/1 and GE 0/0/2 on the Switch.
