Configuring Traffic Filters and Protocol Prioritization

To configure the percent of bandwidth for the priority queues, you edit these

Configuration Manager parameters:

• High Queue Percent Bandwidth

• Normal Queue Percent Bandwidth

• Low Queue Percent Bandwidth

When changing bandwidth allocation, remember that the percent of bandwidth for

the High queue, Normal queue, and Low queue must total 100 percent.

Queue Size

Queue size (or queue depth) is the configurable number of packets that each

priority queue can hold. The default value for bandwidth allocation is 20 packets,

regardless of packet size.

When you set the queue size, you assign buffers (which hold the packets) to each

queue. A queue is full when it exceeds the buffer size. The router discards (clips)

traffic sent to a full queue.

To configure queue size, you edit these Configuration Manager parameters:

• High Queue Size

• Normal Queue Size

• Low Queue Size

• High Water Packets Clear

Queue Size Example

Suppose that you use the default queue size (20 packets) for all three priority

queues. The statistics indicate that the High queue’s Clipped Packets Count is 226,

and its High-Water Packets Mark is 20. This indicates that the High queue has

been full at least once and that the router has discarded 226 packets.

Note:

The buffer size for priority queues is not configurable when using the

strict dequeuing algorithm.
