A
The time the test has been running.
B
Traffic characteristics for the last 1 second, and the average and peak values
since the test began:
•
Utilization: Percentage of the network’s bandwidth used. This indicates the
traffic density on the network. Utilization averaging over 40 % may
indicate a problem.
•
Collisions: The percentage of collision frames as compared to the total
number of frames detected in the last 1 second. Collisions occur when two
devices attempt to transmit at the same time. A collision rate averaging
over 5 % may indicate a problem. A full-duplex link should show 0 %
collisions.
•
Errors: Includes short frames, bad FCS (frame check sequence), late
collisions, and jabber. An error rate above 0 % indicates a problem.
•
Broadcasts: Percentage of frames addressed to all devices. Acceptable
broadcast rates vary among networks.
C
Toggles a sound that indicates the utilization level.
D
Stops the test.
E
Resets all statistics to zero.
