138 APPENDIX A: TROUBLESHOOTING
5 Specify the number of seconds that the test should run using:
DLTest TestDuration <seconds>
If you do not enter a value, the test will run indefinitely. However, use
caution when running the test for a specified duration. The test ends
abruptly as soon as the time duration expires, and a discrepancy between
the number of packets transmitted and the number received may result.
6 Start the loopback test by entering:
DLTest START
If the number of received packets equals or approximately equals the
number of transmitted packets, your line has passed the loopback test. If
your line does not pass the test, verify that the software is configured
correctly. Also, check the number of packets transmitted and the number
of errors by entering:
DLTest STATistics
7 Stop the loopback test by entering:
DLTest Abort
8 Restore the owner of the wide area port you are testing from loopback to
your protocol using:
SETDefault !<port> -PORT OWNer = PPP | FrameRelay | SMDS | Auto
Failure to perform this step causes the port to remain in loopback mode
preventing connectivity through the port. Performing diagnostics on the
port will reveal only that the port is down.
