RED Slope Commands(for 7210 SAS-E devices)
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 <threshold>
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
<threshold> — The percentage of the shared buffer space for the buffer pool at which point the drop
probability comes into affect.
