You can visualize this as the gradient of the line in WRED random drop probability, between the points that correspond to the minimum and maximum thresholds of the WRED configuration.

The gradient of the line is defined by 1 / <mark-probability>.

• A <mark-probability> value of 1 will result in the steepest gradient.
• A <mark-probability> value of 255 will result in the most gentle gradient.

policy

This keyword exists for 'organizational' purposes only, to structure the configuration path for relevant command strings.

qos

This keyword exists for 'organizational' purposes only, to structure the configuration path for relevant command strings.

name <policy-name>

Specifies the name of a QoS policy.

shaper

This keyword exists for 'organizational' purposes only, to structure the configuration path for relevant command strings.

traffic-class <traffic-class>

The ID of the traffic class.

mark-probability <mark-probability>

The maximum value for the inverse packet marking probability filter for a QoS traffic class. That is, to set the rate 1/<mark-probability>. The default value is 10. To understand more about this, see WRED algorithm.
