NIVEO PROFESSIONAL Gigabit Management Switch
User's Manual
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).
This mapping is done by port. And “All” could be selected for every port.
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.
