• If neither endpoint is ECN-capable, the packet may be dropped based on the
WRED drop probability. This behavior is the identical treatment that a packet
receives when WRED is enabled without ECN configured on the router.
When you enable wred ecn, and the number of packets in the queue is above the
maximum threshold, packets are dropped based on the drop probability. This
behavior is the identical treatment a packet receives when WRED is enabled
without ECN configured on the router.
