Monitoring Protocol Prioritization Statistics

To monitor and manage protocol prioritization, you use the Statistics Manager to

view statistics in the wfApplication.wfDatalink.wfProtocolPriorityGroup MIB

object group. For information about using the Statistics Manager to view MIB

objects and create custom screen reports, see Configuring and Managing Routers

with Site Manager.

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 priority queues that become full.)

• Transmitted Packets Count (ATM services only)

The number of packets transmitted for each queue.

• Transmitted Octet Count (ATM services only)

The number of octets transmitted for each queue.

• Packets Count (ATM services only)

The number of packets received and dropped from each queue.

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 priority

queuing configuration. You can reset the High-Water Packets Mark using the

Configuration Manager Edit Protocol Priority Interface window. You can reset

both the Clipped Packets Count and High-Water Packets Mark using the

Statistics Manager.
