Chapter 6: Configuration
Parameter Description
Queue: The queue number (QoS class) for which the configuration applies.
Enable: Check or uncheck this box to enable or disable the WRED function on the switch QoS Queue.
Min. Threshold: Control the lower RED threshold. If the average queue filling level is below this threshold, the drop probability is
zero. This value is restricted to 0–100.
Max. DP1: Control the drop probability for frames marked with drop precedence level 1 when the average queue filling level is
100%. This value is restricted to 0–100.
Max. DP2: Control the drop probability for frames marked with drop precedence level 2 when the average queue filling level is
100%. This value is restricted to 0–100.
Max. DP3: Control the drop probability for frames marked with drop precedence level 3 when the average queue filling level is
100%. This value is restricted to 0–100.
NOTE: RED Drop Probability Function: Figure 6-81 shows the drop probability function with associated parameters.
Figure 6-80. Drop probability function.
Max. DP 1–3 is the drop probability when the average queue filling level is 100%. Frames marked with Drop Precedence Level 0
are never dropped. Min. Threshold is the average queue filling level where the queues randomly start dropping frames. The drop
probability for frames marked with drop precedence level “n” increases linearly from zero (at Min. Threshold average queue filling
level) to Max. DP n (at 100% average queue filling level).

6.15 sFlow Agent
The sFlow collector configuration for the switch can be monitored and modified here. Up to one collector is supported. This page
allows for configuring sFlow collector IP type, sFlow collector IP address, and port number for each sFlow collector.
6.15.1 Collector
The “Current” field displays the currently configured sFlow collector. The “Configured” field displays the new collector
configuration.
