Figure 16.12, “Cable Diagnostics Results form” displays the current value of diagnostic parameters for
the corresponding Ethernet port. This form can be used to set certain cable diagnostic parameters for
the port, as indicated below:
Running
Synopsis: boolean
Whether or not a cable test is currently running on this port
Good Termination
Synopsis: unsigned short integer
The number of times GOOD TERMINATION (no fault) is detected on the cable pairs of the selected
port.
Open
Synopsis: unsigned short integer
The number of times OPEN is detected on the cable pairs of the selected port.
Short
Synopsis: unsigned short integer
The number of times SHORT is detected on the cable pairs of the selected port.
Impedance Mismatch
Synopsis: unsigned short integer
The number of times IMPEDANCE MISMATCH is detected on the cable pairs of the selected port.
PassFailTotal
Synopsis: A string
This field summarizes the results of the cable diagnostics performed so far.
• Pass : the number of times cable diagnostics were successfully completed on the selected port.
• Fail : the number of times cable diagnostics failed to complete on the selected port.
• Total : the total number of times cable diagnostics have been attempted on the selected port.
Run Count
Synopsis: unsigned short integer
Run Count : The total number of iterations
Pass Count
Synopsis: unsigned short integer

16.2.4.1. Running Cable Diagnostics
To start cable diagnostics on a port:
1. Connect a Category 5 or better quality cable to the port under test (PUT).
2. Connect the other end of the cable to a similar network port. For example, connect 100BASE-T port
to a 100BASE-T port, 1000BASE-T port to a 1000BASE-T port.
3. Configure the PUT’s “Runs” count.
4. Configure the PUT’s cable diagnostics State to “Started”.
To stop cable diagnostics on a port:
