Communications or local area network link test
Use the communications or the local area network (LAN) link test to send data to remote equipment using the Ethernet, token-ring, DDI, wireless, SDLC, X.25, or BSC protocols.
This test is useful on multipoint lines to verify that a specific terminal is operating correctly without interrupting normal operation of the other terminals.
To run this test, you must have the line varied on, and you must make a connection with the remote equipment. This is necessary because the functional communications program performs this test. If you are using the BSC protocol and the remote equipment is not an IBM® i system, a service representative is needed at the remote location to start diagnostic programs. When you run a link test against the Local Area Network, you can enter *NONE in the controller description field to test a specific remote adapter address.
If this test completes successfully, all equipment within the communications link is operating correctly.
- The remote device that is being tested
- The remote modem
- The cabling at the remote site
If this test fails and all devices on the line are not operating correctly, run the cable, modem, and I/O adapter tests in the order they are listed on the display for further problem analysis.
