Note: On OCe11102 series adapters beaconing can only be done on one port at a
time. If you enable beaconing on a port, you cannot enable beaconing on
another port until you disable beaconing on the previous port.
Running TDR Tests (10GBASE-T Adapters Only)
The TDR test is a cable diagnostic that can tell you the length of the cable, whether or
not the cable has any defects (open/short), and the distance to the defect; if one exists. It
works by sending a signal down the cable and measuring its reflection.
NVP is a property of the cable that must be known for the TDR test to accurately
calculate the cable length (or distance to defect).
Note: The TDR test requires that the cable be 'down' and quiet. It is best if the cable is
not terminated. If it is terminated, the link partner must not be active during the
test.
You can run TDR tests from the Diagnostics Tab when you select a 10GBASE - T
adapter in the discovery-tree.
To run a TDR test:
1. From the discovery-tree, select the 10GBASE-T adapter on which you want to run
the test.
2. Select the Diagnostics tab.
3. Assign the NVP and click Apply.
4. Click Start TDR Test.
Saving the Log File
You can save the test log to a log file for later viewing or printing. When new data is
written to a saved file, the data is appended to the end of the file. Each entry has a
two-line header that contains the identifier of the adapter being tested and the date and
time of the test. Over time, the data accumulates to form a chronological history of the
diagnostics performed on the adapter. (Not available in read-only mode.)
