Configuring Traffic Filters and Protocol Prioritization

2-8

Tuning Protocol Prioritization

Protocol prioritization defaults are designed to work well for most conﬁgurations.

However, you can customize protocol prioritization parameters to maximize its

impact in your network.

To set protocol prioritization tuning parameters, use the Edit Protocol Priority

Interface window. Refer to “Editing Protocol Prioritization Parameters” later in

this chapter for instructions.

Monitoring Statistics

To monitor and manage the impact of protocol prioritization, use the Statistics

Manager to view statistics in the MIB object group

wfApplication.wfDatalink.wfProtocolPriorityGroup. For information on using the

Statistics Manager to view MIB objects and create custom screen reports, refer to

Managing Routers and BNX Platforms.

To determine whether there are enough buffers in each priority queue for the

trafﬁc ﬂow on your network, use the Statistics Manager to examine the following

protocol prioritization statistics:

• High Water Packets Mark — The greatest number of packets that have been in

each queue.

• Clipped Packets Count — The number of packets that have been discarded

from each queue. (The router discards packets from full priority queues.)

Generally, if a queue’s Clipped Packets Count is high and the High Water Packets

Mark is close to its queue size, that queue does not have enough buffers.

Note: To determine whether statistics reﬂect a transient event, you may want

to reset the statistics and check again later before changing the conﬁguration

of priority queuing. You can reset the High Water Mark in Site Manager’s Edit

Protocol Priority Interface window. You can reset both the Clipped Packets

Count and High Water Packets Mark using the Statistics Manager.
