Description
Use the qos wred command to apply WRED at an interface.
Use the undo qos wred command to restore the default dropping method.
By default, the dropping method of a queue is tail drop.
As WRED in interface view cannot be used independently or with the queuing methods
but WFQ, apply WFQ to the interface before enabling WRED on it.
Related command: qos wfq, qos wred, display qos wred interface.

# Apply WRED at Ethernet0/0/0 interface. (Provided that WFQ has already been
applied at the interface).
