random-detect exponential weighting-constant
Use this command to configure the WRED decay exponent for a CoS queue interface.
no random-detect exponential weighting-constant
Use this command to reset the WRED decay exponent to the default value on all interfaces or one
interface.
random-detect queue-parms
Use this command to configure WRED parameters for each drop precedence level supported by a
queue. Use it only when per-COS queue configuration is enabled (using the cos-queue
random-detect command).
• min-thresh is the minimum threshold the queue depth (as a per
centage) where WRED
starts marking and dropping traffic.
• max-thresh is the maximum threshold is the queue depth (as a per
centage) above which
WRED marks / drops all traffic.
• drop-probability is the perc
entage probability that WRED will mark/drop a packet,
when the queue depth is at the maximum threshold. (The drop probability increases linearly
from 0 just before the minimum threshold, to this value at the maximum threshold, then goes
to 100% for larger queue depths). Each parameter is specified for each possible drop
precedence ("color" of TCP traffic).
The last precedence applies to all non-TCP traffic. For example, in a 3-color system, four
par
ame
ters are specified: green TCP, yellow TCP, red TCP, and non-TCP, respectively.
