4. In the Test Duration field, type the test duration time (in minutes).
5. Click <Apply> to begin the loopback test on the port.
The new loopback status of the port appears in the dialog box.
This dialog will be updated by traps and polling while it is open.
Only one loopback test at a time may exist on a specified port. Therefore,
if a loopback test is already running on a specific port, you can select only
No Loopback for this port.
If the Administrative Status of the selected port is down, then no
loopback will be available. A message will be displayed at the status bar
saying “Diagnostics are not available for interface that its Administrative
Status is Down.”
Upon clicking <Apply>, the NMS checks if the value of Test Duration is
within the valid range. If not, the following message will be displayed on
Status Bar: "Test Duration (min.) value should be between 1 and 255"
and the operation will not be performed.
6. Click <Close> to close the Port Loopback Test dialog box.
