Test Facility
This section introduces the Test Facility. The Test Facility is built into all
AT-8600 Series software. For detailed information on operating the Test
Facility, see the Test Facility chapter of the AT-8600 Series Software Reference.
The Test Facility is designed to test the switch’s physical interfaces. Testing
should not be performed while the switch is operational as the presence of a
loopback plug may cause feedback of network traffic. Also, any interfaces
being tested are dedicated to the Test Facility. The Test Facility can be thought
of as a specialised interface module like PPP or Frame Relay.
10/100 Ethernet LAN Port Tests
A loopback plug is required to run the first part of the Ethernet LAN test. See
“Loopback Plugs for Testing Switch Interfaces” on page 22 for details of how to
make a loopback plug. To start an Ethernet interface test, use the command:
enable test int=portn
where n is the Ethernet interface number. The test will run for 4 minutes. Use
the show test command to observe the test progress.
Test results are displayed with the command:
show test
