Network Traffic Monitoring - DTX-NSM

The DTX-NSM CableAnalyzers Traffic Monitor enables you to identify active cables and monitor a networks basic health.
 
The following Traffic characteristics are monitored: 
  • Utilization
  • Collisions
  • Errors
  • Broadcasts
 
Procedure: 
  1. Turn the dial to MONITOR
  2. Highlight Network Connectivity 


  3.  press TEST


  4. Connect the Cable or Fiber to the DTX-NSM
  5. Press TEST 


  6. The Traffic option is now available for monitoring the network
  7. Press F1Traffic
  8. The Traffic Monitor screen will display with the networks information 


Here is a list of definitions:

 
Running
The time the test has been running.
 
Type
Traffic characteristics for the last 1-second and the average and peak values since test began.
 
Utilization
Percentage of the networks 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.
 
Sound on
Toggles a sound that indicates the utilization level
 
Stop
Stops the test
 
Reset
Resets all statistics to zero
