WRED Overview (CLI)
Weighted Random Early Detection (WRED) enables differentiation between
higher and lower priority traffic based on CoS. You can define up to 30 WRED
profiles. Each profile contains a green traffic curve and a yellow traffic curve.
These curves describe the probability of randomly dropping frames as a function
of queue occupancy.
The system also includes two pre-defined read-only profiles. These profiles are
assigned WRED profile IDs 31 and 32:
•
Profile number 31 defines a tail-drop curve and is configured with the
following values:
100% Yellow traffic drop after 64kbytes occupancy.
100% Green traffic drop after 128kbytes occupancy.
Yellow maximum drop is 100%
Green maximum drop is 100%
•
Profile number 32 defines a profile in which all will be dropped. It is for
internal use and should not be applied to traffic.
