Commands

This command sets the WRED parameters for each drop precedence level supported by a queue. The actual number of queue drop precedence levels is platform-specific (S2410 has four). Use the no form of this command to restore the default values for the queue WRED parameters.

queue-id-1 [queue-id-2	Enter a queue ID from 0 to 3. Enter from one ID up to four.
… queue-id-n]	Range: 0 to 3
min-thresh 0-160-16	Enter the keyword min-threshfollowed by the desired minimum
0-16	threshold value for each associated queue (first threshold value is
	associated with queue 1, etc.).
	Range: 1 to 16
max-thresh 0-160-16	Enter the keyword max-threshfollowed by the desired maximum
0-16	threshold value for each associated queue.
	Range: 1 to 16

0-15 0-15	value for each associated queue. See Usage, below.
	Range: 1 to 15
Global Config

The drop-prob-scalevalue is the WRED (weighted random early discard) drop probability scale factor expressed as an integer. This value, S, specifies that one out of every (2**S) packets are dropped by WRED when the average queue length reaches its maximum threshold value.
