portLoopbackTest
Figure B-44 shows the portLoopbackTest command which is used to
validate the data path to the optical interface and is intended to verify that the
G_port or FL_Port interface card is error free. This is an internal test and
checks all of the Switch’s internal firmware and circuitry.
The command syntax is portLoopbackTest nFrames .
This command may not be executed on an operational Switch. Before issuing
portLoopbackTest , disable the Switch using the switchDisable
command
If you do not include the nFrames parameter the loopback test runs
continuously until you press Return again. If the test does not find an error
there is no output. You can choose to continue the test, view statistics, or view
an error log. Table B-14 shows the loopback errors message fields.
While the test is running, all interface module front panel LEDs rapidly flicker
green indicating that the test is finding no errors and is processing. After
issuing portLoopbackTest, you can choose to continue the test, view statistics,
or view an error log.
