This command turns Explicit Congestion Notification (ECN) on or off for the corresponding QoS profile for the given port(s).
|qp_num||QoS profile (qp1, qp2, qp3, qp3, qp4, qp5, qp6, qp7, qp8)|
|wred||Designates weighted random early detection (WRED).|
|port_list||Selects specific ports to apply the ECN setting for the designated QoS profile.|
|all||Selects all ports to apply the ECN setting for the designated QoS profile.|
Weighted Random Early Detection (WRED) drops the packets, based on the average length exceeding a specific threshold value to indicate congestion. Explicit Congestion Notification (ECN) is an extension to WRED that marks the drop-eligible packets, instead of dropping, using the same criteria of minimum threshold, maximum threshold, and drop probability
The following example enables ECN for QoS profile 5 on port 2:
# configure qosprofile egress qp5 wred ecn on ports 2
