Test Facility

The test facility is a hardware test tool in the AlliedWare operating system. Its
primary function is to validate that there are no hardware problems after
installation of the switch or expansion options. You can also use it as a
troubleshooting tool, but it is just one of many such tools. You could consider
the test facility to be a specialised interface module, such as PPP or Frame
Relay, where the interfaces under test are dedicated to the test facility.
Before you use the test facility, disable configurations by using the
set configuration=none command, and restart or reboot the switch. For more
information about the test facility, see the Test Facility chapter in the
®
AlliedWare Operating System Software Reference.

Testing Ethernet LAN Ports

A crossover cable is required to run an Ethernet LAN test. How to make a
suitable cable is described in
page 31. To start the test, loop a four-pair crossover or straight-through cable
between two RJ-45 ports and enter the enable test interface=all command.
Interfaces connected by crossover cables are tested. If a test fails, contact your
authorised Allied Telesis distributor or reseller.
To display test results, use the show test command. To display detailed output
with frame counts, use the show test count command. For example output
from these commands, see the Test Facility chapter in the AlliedWare
System Software Reference. This chapter also contains information on how to test
other interfaces.
