Slope QoS Commands
queue
Syntax queue queue-id drop-rate num
no queue queue-id
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
ues, on page
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.
drop-rate num — Specifies the drop rate to be configured.
