Asynchronous Interface Tests
Asynchronous interfaces require a loopback plug to be installed before the test
will operate. See “Cables And Loopback Plugs” on page 75 for details of how to
make a loopback plug. To start a test of an asynchronous interface, use the
command:
ENABLE TEST INT=PORT n
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 your router’s Software
Reference), to observe the test progress.
Ethernet LAN Interface Tests
The Test Facility will not test Ethernet interfaces on AT-AR026 PICs.
A loopback plug is required to run the first part of the Ethernet LAN test. See
“Cables And Loopback Plugs” on page 75 for details of how to make a loopback
plug. To start a test of an Ethernet interface, use the command:
ENABLE TEST INT=ETH n
where n is the Ethernet interface number. This will run the test for 4 minutes.
Use the SHOW TEST command (from the Test Facility chapter of your router’s
Software Reference), to observe the test progress.
WAN Port Tests
To fully test synchronous interfaces, an external tester (available from your
authorised Allied Telesyn 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=SYN n
or
ENABLE TEST INT=BRI n
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 your router’s
Software Reference), to observe the test progress.
If a test fails, please contact your authorised Allied Telesyn distributor or reseller.
