    The AUI port is first tested by transmitting packets and checking for “no carrier” or response packets. If the AUI test fails, the TPE port is then tested. SPARCstation 4/Xterminal 1 Service Manual • January 1995...

You may see these watch-aui messages: ok watch-aui Using AUI Ethernet Interface Lance register test -- succeeded Internal loopback test -- succeeded External loopback test -- Lost Carrier (transceiver cable problem?) send failed. You may also control the selection of Ethernet interfaces to monitor by using specific commands.
