What is the difference between
TX WRED threshold and
TX drop threshold

For example, with the default value:

Tx drop thresholds:
Queue #  Thresholds - percentage
-------  -------------------------------------
1        80% 100%
2        80% 100%

Tx WRED thresholds:
Queue #  Thresholds - percentage
-------  ------------------------------------------
1        80% 100%
2        80% 100%

In the queue 1, threshold 1 start drops packets when buffer reaches 80%.

The frames that will trigger the threshold 1, queue 1 is CoS 0 1 for both
cases

Even that, after start drop, the congestion management will discard any
frames - CoS 0 1,  CoS 2 3 and so on, in the case WRED is not supported

Am I right ?

Thanks
