DSCP mode QoS:
The DSCP mode QoS gives packet priority by the types of the incoming
packets. We distinguish those packets according to the “Delay”,
“Throughput” and “Reliability” information attaching on the packet. The
types are listed as the following table:
Bit 0 (Delay) Bit 1 (Throughput) Bit 3 (Reliability)
0 (Normal) 0 (Normal) 0 (Normal)
1 (Low) 1 (High) 1 (High)
Note: The device distinguishes packets with DSCP precedence
“000(routine)” only.
To configure DSCP Based QoS configuration:
1. Select “DSCP” in the “Mode” column for those ports that are going to
perform DSCP-based QoS. Click the “Apply” button.
2. Click the “DSCP priority” button. The “DSCP Priority Setting” page
shows up.
3. Give the priorities as high or low for each precedence types.
4. Click the “Apply” button again to execute your configuration.
