Syntax queue queue drop-rate drop-rate
no queue queue-id queue
Context config>qos>slope-policy>high-slope
config>qos>slope-policy>low-slope
Description
The drop-rate num parameter is expressed as a scalar number, and mapping to the percent of
packets dropped in congestion conditions is specified in Table 41, Drop Rate Value to Percent
Mapping Values, on page 103.
The no form of this command restores the drop-rate value to the default setting.
Default
drop-rate 1 — High slope default is 1 (6.25 drop-rate) for all the queues, this implies that once the
shared buffer utilization reaches the start-threshold level then packets egressing out from a
particular queue would be dropped at 6.25% rate.
drop-rate 0 — Low slope default is 0 (100% drop-rate) for all the queues, this implies that once the
shared buffer utilization reaches the start-threshold level then packets egressing out from a
particular queue would be dropped at 100% rate.
Parameters queue-id —
Specifies the ID of the queue for which the drop-rate is to be configured.
Values 1 — 8
drop-rate num —
Specifies the drop rate to be configured.
Values 0 — 7
