Quidway S8500 Series Routing Switches
yellow-min-threshhold: Minimum queue length to trigger random yellow packet
dropping, in the range of 0 to 65535. It must be a multiple of 256 bytes.
yellow-max-threshhold: Queue length to trigger complete yellow packet dropping, in
the range of 0 to 65535. It must be a multiple of 256 bytes.
yellow-max-prob: Maximum drop probability for yellow packets, in the range of 1 to 15.
red-min-threshhold: Minimum queue length to trigger random red packet dropping, in
the range of 0 to 65535. It must be a multiple of 256 bytes.
red-max-threshhold: Queue length to trigger complete red packet dropping, in the
range of 0 to 65535. It must be a multiple of 256 bytes.
red-max-prob: Maximum drop probability for green packets, in the range of 1 to 15.
exponent: Weight for calculating average queue length, in the range of 1 to 15. By
default, it is 9.
Description
Use the queue command to configure parameters for a WRED index.
Use the undo queue command to restore the default parameters for the WRED index.
The switch provides four sets of default WRED parameters, respectively numbered as
0, 1, 2 and 3. Each set includes 80 parameters, 10 parameters for each of the eight
queues. The ten parameters are green-min-threshhold, yellow-min-threshhold,
red-min-threshhold,
red-max-threshhold, green-max-prob, yellow-max-prob, red-max-prob and exponent.
You can use the command to modify the parameters of a specific WRED index.
Example
# Configure parameters for WRED 0: queue-id is 7; green-min-threshold is 150;
green-max-threshold is 500; green-max-prob is 5; yellow-min-threshold is 100;
yellow-max-threshold is 150; yellow-max-prob is 10; red-min-threshold is 50;
red-max-threshold is 100; red-max-prob is 15; exponent is 10.
