Troubleshooting
test port modem back-to-back slot/port slot/port [num-packets]—Performs internal back-to-back port
tests between two ports, sending test packets of the specified size.
You might need to execute this command on several different combinations of ports to determine which
one is not functioning properly. A pair of operable ports successfully connects and transmits data in both
directions. An operable port and an inoperable port do not successfully connect with each other.
A sample back-to-back test might look like the following:
AS5400# test port modem back-to-back 2/10 3/20
Repetitions (of 10-byte packets) [1]:
*Mar
back-to-back test:CONNECT33600/V34/LAP
*Mar
back-to-back test:success/packets = 2/2
A port that has been confirmed to have problems can often be fixed using the clear spe command. For
more information, see the
The results of the test port modem back-to-back command are displayed in the show port modem test
command output:
AS5400# show port modem test
