	Field Reference
Table K-95	QoS Class Dialog Box—Queuing and Congestion Avoidance Tab
Element			Description
Enable Queuing and			When selected, enables you to define queuing parameters for the selected
Congestion Avoidance			QoS class.
			When deselected, disables all queuing options for the selected QoS class.
			Note Queuing is available only for output traffic. Available queuing
			options depend on whether you are defining a specific QoS class or
			the default class.
Priority			Applies only when you are defining a specific QoS class for priority traffic
			(for example, voice traffic).
			The amount of bandwidth on this interface allocated to high-priority traffic.
			You can define this amount by:
			• Percentage—Valid values range from 0 to 100%.
			• Kbit/sec—Valid values range from 8-2000000 kilobits per second.
			Low-Latency Queuing, page 15-158(LLQ) ensures that priority traffic
			receives this defined bandwidth.
			Note You can define this option for one class only per interface. If you
			select this option, the Shaping tab is disabled.
Fair Queue			Applies only when you are defining the default class.
			The number of dynamic queues to reserve for this class. By default, this
			number is based on the available bandwidth of the selected interface. Values
			range from 16 to 4096, based on powers of 2. For more information, see
			Table 15-7 on page 15-159.
			Note Failure to provide a sufficient number of queues for the default class
			(a condition known as starvation) could result in the traffic not being
			sent.
