DSCP priority operation will use the priority setting in ToS field of IP packets for

QoS operation.

Seven DSCP values (0~63) could be defined and map to priority queues (High

/Middle/Normal/Low).

If DSCP priority function is enabled, these settings will be followed for QoS

operation.

2). Queue Mode

This switch supports Strict Priority and WRR (Weight Round Robin) operation for

sending out packets from piority queues.

If Strict Priority is selected, packets in higher priority queues will always get

bandwidth service first. Lower priority queues will get service when higher

priority queues are empty.

If WRR is selected, priority queues will be served with the weighting of priorities.

And the setting of weight could be configured at “Queue Scheduling”.
