Quality of Service Guide Slope QoS Policies
Edition: 01 3HE 11014 AAAC TQZZA 373
For example, configuring a DP to be 74% means that the actual value used is 50%.
The no form of this command restores the max-prob value to the default setting.
Default max-prob 80 (80% maximum drop probability corresponding to the max-avg)
Parameters percent — the maximum drop probability percentage corresponding to the max-avg,
expressed as a decimal integer
Values 0 to 100
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 WRED/RED slope.
By default, all slopes are shut down and have to be explicitly enabled (no shutdown).
The no form of this command administratively enables the WRED/RED slope.
Default shutdown (the WRED/RED slope disabled, implying a zero (0) drop probability)
start-avg
Syntax start-avg percent
no start-avg
Context config>qos>slope-policy>high-slope
config>qos>slope-policy>low-slope
Description This command sets the high-priority or low-priority WRED/RED slope position for the queue
average usage value where the packet discard probability starts to increase above zero
(minThreshold or minT). The percent parameter is expressed as a percentage of the
maximum queue depth (buffer-based WRED) or a percentage of maximum payload of the
queue (payload-based WRED).
The no form of this command restores the start-avg value to the default setting. If the
max-avg setting is smaller than the default, an error will occur and the start-avg setting will
not be changed to the default.
Parameters percent — the percentage of the maximum queue depth where the packet discard
probability starts to increase above zero
Values 0 to 100
Default 50
