A sample diagnostic autotest setting the time at 12:45 and at 8 hour intervals looks like the following:
AS5400(config)# port modem autotest time 12:45 8

SPE Back-to-Back Test
When an SPE port is tested as Bad, you may perform additional testing by conducting a series of internal
back-to-back connections and data transfers between two SPE ports. All port test connections occur
inside the gateway. For example, if mobile users cannot dial into port 2/5 (the sixth port on the universal
port card in the second chassis slot), attempt a back-to-back test with port 2/5 and a known-functioning
port such as port 2/6.
Enter the following command in privileged EXEC mode (the prompt is displayed as
AS5400#
You might need to enable this command on several different combinations of ports to determine which
one is not functioning properly. A pair of operable ports successfully connect and complete transmitting
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's output:
AS5400# show port modem test
