QoS
Global Configuration
1. QoS: Click “QoS” drop-down menu from “QoS” drop-down list to choose
“Enable” or “Disable” to enable or disable QoS.
2. Trust: Enable or disable the switch port to trust the CoS (Class of
Service) labels of all traffic received on that port. Enable or disable a
routed port to trust the DSCP (Differentiated Service Code Point) labels
of all traffic received on that port.
3. Policy: Choose “Strict Priority(Queue3) + WRR(Queue0-2)” or
“WRR(Queue0-3)”. A strict priority queue is always emptied first. The
queues that are used in the WRR (Weighted Round Robin) are emptied
in a round−robin fashion, and you can configure the weight for each
queue.
4. Weighted Round Robin: Click in the “Weight(1~55)” textbox and specify
a new number from 1 ~ 55 for Queue 0 ~ 3.
5. Submit: Click “Submit” button when you finished Global Configuration.
