Transition Networks SISPM1040-3xxx-L Web User Guide 9-10 WRED This page lets you configure the Random Early Detection (RED) settings. Through different RED configuration for the queues it is possible to obtain Weighted Random Early Detection (WRED) operation between queues. The settings are global for all ports in the switch. WRED (Weighted Random Early Detection) is an active queue management mechanism that provides preferential treatment of higher priority frames when traffic builds up within a queue. A frame's DPL is used as input to WRED. A higher DPL assigned to a frame results in a higher probability that the frame is dropped during times of congestion. Web Interface To configure and display the Random Early Detection in the web interface: 1. Click QoS and WRED. 2. Set Enable, Min, and Max parameters. 3. In the Max Unit column select Fill Level or Drop Probability. The default is Fill Level. 4. Click the Apply button to save the settings. 5. To cancel the settings click the Reset button. It will revert to previously saved values. Figure 7-10: Weighted Random Early Detection Configuration Parameter descriptions: Group : The WRED group number for which the configuration below applies.
