Transition Networks SISPM1040-3xxx-L Web User Guide Chapter 9 - Quality of Service (QoS) The switch supports four QoS queues per port with strict or weighted fair queuing scheduling. It supports QoS Control Lists (QCL) for advance programmable QoS classification, based on IEEE 802.1p, Ethertype, VID, IPv4/IPv6 DSCP and UDP/TCP ports and ranges. QoS provides high flexibility in the classification of incoming frames to a QoS class. The QoS classification looks for information up to Layer 4, including IPv4 and IPv6 DSCP, IPv4 TCP/UDP port numbers, and user priority of tagged frames. This QoS classification mechanism is implemented in a QoS control list (QCL). The QoS class assigned to a frame is used throughout the device for providing queuing, scheduling, and congestion control guarantees to the frame according to what was configured for that specific QoS class. The switch supports advanced memory control with excellent performance of all QoS classes under any traffic scenario, including jumbo frame. A super priority queue with dedicated memory and strict highest priority in the arbitration. The ingress super priority queue allows traffic recognized as CPU traffic to be received and queued for transmission to the CPU even when all the QoS class queues are congested. 9-1 Port Classification This page lets you configure basic QoS Ingress Classification settings for all switch ports. Web Interface To configure QoS Ingress Port Classification parameters via the web UI: 1. Click QoS and Port Classification. 2. Select QoS Ingress Port parameters. 3. Click the Apply button to save the settings. 4. To cancel the settings click the Reset button. It will revert to previously saved values. 5. Click "PCP Classification" to go to the next page "Port PCP Classification". 33763 Rev. G Figure 9-1: QoS Ingress Port Classification https://www.transition.com Page 145 of 496
