Slope QoS Policy Command Reference
Description Sets the exceed, low, or high Random Early Detection (RED) slope position for the shared buffer
average utilization value where the packet discard probability rises directly to one. The percent
parameter is expressed as a percentage of the shared buffer size.
The no form of this command restores the max-avg value to the default setting. If the current start-avg
setting is larger than the default, an error will occur and the max-avg setting will not be changed to the
default.
Default max-avg 90 — High slope default is 90% buffer utilization before discard probability is 1.
max-avg 75 — Low slope default is 75% buffer utilization before discard probability is 1.
max-avg 55 — Exceed slope default is 55% buffer utilization before discard probability is 1.
Parameters
percent — The percentage of the shared buffer space for the buffer pool at which point the drop

Description Sets the exceed, low, or high Random Early Detection (RED) slope position for the maximum non-one
packet discard probability value before the packet discard probability rises directly to one. The percent
parameter is expressed as a percentage of packet discard probability where always discard is a
probability of 1. A max-prob value of 80 represents 80% of 1, or a packet discard probability of 0.8.
The no form of this command restores the max-prob value to the default setting.
Default max-prob 80 to 80% maximum drop probability corresponding to the max-avg.
Parameters percent — The maximum drop probability percentage corresponding to the max-avg, expressed

probability becomes 1. The value entered must be greater or equal to the current setting of
start-avg. If the entered value is smaller than the current value of start-avg, an error will
occur and no change will take place.
