Using Protocol Prioritization Queues

To tune priority queuing with the bandwidth allocation algorithm, consider

adjusting the following configuration defaults:

• Percent of Bandwidth

• Queue Size

To tune priority queuing with the strict dequeuing algorithm, consider adjusting

the following configuration defaults:

• Queue Size

• Latency

Percent of Bandwidth

When using the bandwidth allocation algorithm, you can change the default

allocation of bandwidth for each of the three priority queues.

Queued traffic with large packets often requires more than the default bandwidth

allocation. For example, if statistics indicate that one interface requires more than

70 percent of bandwidth to properly transmit high-priority traffic, you can

increase the High Queue Percent Bandwidth parameter and decrease the Normal

or Low Queue Percent Bandwidth parameter.

Note:

If statistics indicate that the High queue does not have enough buffers,

consider reducing the amount of high-priority traffic. You should be selective

in assigning high-priority status. Too many traffic types with high-priority

status can defeat the purpose of protocol prioritization. With the strict

dequeuing algorithm, too much high-priority traffic can result in discarding (or

clipping) normal- and low-priority traffic.
