RED Slope Commands
shutdown
Syntax [no] shutdown
Context config>qos>slope-policy>high-slope
config>qos>slope-policy>low-slope
Description This command enables or disables the administrative status of the Random Early Detection slope.
By default, all slopes are shutdown and have to be explicitly enabled (no shutdown).
The no form of this command administratively enables the RED slope.
Default
shutdown - RED slope disabled implying a zero (0) drop probability
start-threshold
Syntax start-threshold percent
no start-threshold
Context config>qos>slope-policy>high-slope
config>qos>slope-policy>low-slope
Description This command sets the low priority or high priority Random Early Detection (RED) slope position for
the shared buffer instantaneous utilization value where the packet discard probability comes into
affect. The percent parameter is expressed as a percentage of the shared buffer size.
The no form of this command restores the start-threshold value to the default setting.
Default
start-threshold 75 — High slope default is 75% buffer utilization before discard probability comes
into affect.
start-threshold 50 — Low slope default is 50% buffer utilization before discard probability comes
into affect.
Parameters
percent — The percentage of the shared buffer space for the buffer pool at which point the drop

probability comes into affect.
Values
0 — 100
