QoS Class Dialog Box—Queuing and Congestion Avoidance Tab
Use the Queuing and Congestion Avoidance tab of the QoS Class dialog box to
perform Class-Based Weighted Fair Queuing (CBWFQ) on the output traffic in
the selected QoS class. Queuing prioritizes traffic and manages congestion on
your network by determining the order in which packets are sent out over an
interface.
The fields displayed in the Queuing tab depend on whether you are defining a
specific QoS class or the default class.
Note The Queuing and Congestion Avoidance tab is unavailable when you define a QoS
policy on the control plane or on input traffic.
Navigation Path
Go to the QoS Class Dialog Box, page K-205, then click the Queuing and
Congestion Avoidance tab.
