The network metrics are useful for evaluating network performance and troubleshooting.
Illustration 4–3 Diagnostic metrics
Interpreting the diagnostic data
Even the best designed and installed network will have minor or infrequent communications
issues. The following tips will help determine the significance of the network metric as well
as suggestions for improvement.
Tx and Rx Frame Counts The actual number of frame counts depends on the baud rate and
number of network devices. The more connected devices, the slower the frame counts
grow. Unless the relative difference between the two counts is greater than 10%, the network
is generally okay. The reason is the router sends more messages than it receives is primarily
because of the small gap between its own MAC address and the next device.
