Configuring Quality of Service Configuring QoS - General 20 Interface QoS Settings The Interface Settings page enables configuring QoS on each port of the switch, as follows: QoS State Disabled on an Interface-All inbound traffic on the port is mapped to the best effort queue and no classification/prioritization takes place. QoS State of the Port is Enabled-Port prioritize traffic on ingress is based on the system wide configured trusted mode, which is either CoS/ 802.1p trusted mode or DSCP trusted mode. To enter QoS settings per interface: STEP 1 Click Quality of Service > General > Interface Settings. The Interface Settings page is displayed. STEP 2 Select Port or LAG to display the list of ports or LAGs. The list of ports/LAGs is displayed. QoS State displays whether QoS is enabled on the interface. STEP 3 Select an interface, and click Edit. The Edit QoS Interface Settings is displayed. STEP 4 Select the Port or LAG interface. STEP 5 Click to enable or disable QoS State for this interface. STEP 6 Click Apply. The Running Configuration file is updated. Configuring QoS Queues The switch supports four queues for each interface. Queue number four is the highest priority queue. Queue number one is the lowest priority queue. There are two ways of determining how traffic in queues is handled, Strict Priority and Weighted Round Robin (WRR). Strict Priority-Egress traffic from the highest-priority queue is transmitted first. Traffic from the lower queues is processed only after the highest queue has been transmitted, thus providing the highest level of priority of traffic to the highest numbered queue.
