RED Slope Commands
max-avg
Syntax
max-avg percent
no max-avg
Context
config>qos>slope-policy>queue>high-slope
config>qos>slope-policy>queue>low-slope
config>qos>slope-policy>queue>non-tcp-slope
Sets the low priority or high priority or non-tcp Weighted Random Early Detection (WRED) slope
Description
position for the reserved and 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
startavg setting is larger than the default, an error will occur and the max-avg setting will not be
changed to the default.
max-avg 90 — High slope default is 90% buffer utilization before discard probability is 1.
Default
max-avg 75 — Low slope default is 75% buffer utilization before discard probability is 1.
max-avg 75 — Non-tcp slope default is 75% buffer utilization before discard probability is 1.
percent — The percentage of the reserved and shared buffer space for the buffer pool at which point the
Description
drop 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.
Values
max-prob
Syntax
max-prob percent
no max-prob
Context
config>qos>slope-policy>queue>high-slope
config>qos>slope-policy>queue>low-slope
config>qos>slope-policy>queue>non-tcp-slope
Sets the low priority or high priority Random Early Detection (RED) slope position for the
Description
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.
