Queue-Scheduler - 3Com 8807 Command Reference Manual

QoS Commands 261
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, green-max-threshhold,
yellow-max-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.
