Configuring Traffic Filters and Protocol Prioritization
2-12 117348-A Rev. A
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.
From this information, you can conclude that you have not assigned enough
buffers to the High queue for the amount of high-priority traffic on this interface.
To prevent additional high-priority traffic from being discarded, you can
reconfigure the size of the queues or reevaluate the amount of traffic assigned to
the High queue.
Reconfiguring Queue Size
Suppose that you now look at the statistics of the Normal and Low queues and
find that the Low queue has a Clipped Packets Count of zero and a High-Water
Packets Mark of 06 (F
igure 2-4). Therefore, you can conclude that there have
never been more than six packets in the Low queue, and the router has not
discarded any low-priority packets.
Figure 2-4. Priority Queue Statistics for the Queue Size Example
In this case, you may choose to decrease the Low queue size to 10, and increase
the High queue size to 30 (F
igure 2-5).
