Queueing
Queueing is for Congestion Management.
Custom Queueing:
With CQ, bandwidth is allocated proportionally for each different class of
traffic, By default, each cycling, dequeque 1500 bytes for each queue. CQ allows you to specify the number of bytes or packets to be drawn from the queue

Configuration: queue-list command, then apply under interface using custom-queue-list
• Defining the Custom Queue List (Required)
• Specifying the Maximum Size of the Custom Queues (Optional)
• Assigning Packets to Custom Queues (Required)
• Monitoring Custom Queue Lists (Optional)
Class-Based Weighted Fair Queueing (CBWFQ)Class-based weighted fair queueing (CBWFQ) extends the standard WFQ functionality to provide support for user-defined traffic classes. For CBWFQ, you define traffic classes based on match criteria including protocols, access control lists (ACLs), and input interfaces.
First In First Out (FIFO) QueueingFirst In, First Out (FIFO) Queueing—Packets are forwarded in the same order in which they arrive at the interface. \
Internet Protocol Real-Time Protocol Priority (IP RTP Priority)The Frame Relay IP RTP Priority feature provides a strict priority queueing scheme on a Frame Relay permanent virtual circuit (PVC) for delay-sensitive data such as voice.
Low Latency Queuing (LLQ)The Low Latency Queueing feature brings strict priority queueing to Class-Based Weighted Fair Queueing (CBWFQ).
Priority Queuing (PQ)PQ ensures that important traffic gets the fastest handling at each point where it is used. It was designed to give strict priority to important traffic.
Weighted Fair Queuing (WFQ)WFQ is one of Cisco's premier queuing techniques. It is a flow-based queuing algorithm that does two things simultaneously: It schedules interactive traffic to the front of the queue to reduce response time, and it fairly shares the remaining bandwidth between high bandwidth flows.
