Asynchronous
Interface Tests
Asynchronous interfaces require a loopback plug to be installed before the test
will operate. See “Cables and Loopback Plugs” on page 51 for details of how to
make a loopback plug. To start a test of an asynchronous interface, use the
command:
enable test int=portn
where n is the interface number. This will run the test for 4 minutes. Use the
show test command (from the Test Facility chapter of the Software Reference),
to observe the test progress.
Ethernet Interface
Tests for Switch and
Eth Ports
A loopback plug is required to run the first part of the Ethernet test on eth ports
and switch ports. See “Cables and Loopback Plugs” on page 51 for details of
how to make a loopback plug.
To start a test of an Eth interface, use the command:
enable test int=ethn
where n is the Ethernet interface number.
To start a test of a switch port interface, use the command:
enable test int=portn
where n is the switch port number.
This will run the test for 4 minutes. Use the show test command (from the Test
Facility chapter of the Software Reference), to observe the test progress.
AR770S To test an eth port on the AR770S in 1000 Mbps mode, loop the port
back to the other eth port. To test a switch port in 1000 Mbps mode, loop the
port back to another switch port. In 10 Mbps or 100 Mbps mode, either loop the
port back to another port, or use a loopback plug. If two or more ports are
looped back to each other, you must test both ports at the same time. Use the
command:
enable test int=base
AR026 PIC The Test Facility does not test Ethernet interfaces on AT-AR026
PICs.
WAN Port Tests To fully test synchronous interfaces, an external tester (available from your
authorised Allied Telesis distributor or reseller) is required. A loopback plug is
not required to test BRI interfaces.
To start a WAN interface test, use the command:
enable test int=synn
or
enable test int=brin
where n is the WAN interface number. This will run the test for 4 minutes. Use
the show test command (from the Test Facility chapter of the Software
Reference), to observe the test progress.
