WRED Queue

This window is used to view and configure the WRED feature's queue settings. WRED drops packets,
based on the average queue size exceeding a specific threshold, to indicate congestion. Explicit
Congestion Notification (ECN) is an extension to WRED in that ECN marks packets instead of dropping
them when the average queue size exceeds a specific threshold value. When configuring the WRED
ECN feature, routers and end hosts would use this marking as a signal that the network is congested and
slow down sending packets.
To view the following window, click QoS > WRED > WRED Queue, as shown below:
