Appendix D FORTH Diagnostics D-5
For example:
SPARCstation 5 systems have two types of Ethernet interfaces, 10BASE-T (also called
twisted-pair Ethernet or TPE) and 10BASE5 (also called thick Ethernet or AUI). Only
one Ethernet interface may be connected at a time. The system can automatically
select which interface is connected and active.
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.
Entering watch-aui causes this automatic selection to take place. You may see
these messages:
You may also control the selection of Ethernet interfaces to monitor by using specific
commands. Use watch-tpe to monitor the 10BASE-T (TPE) connection or watch-
aui to monitor the 10BASE5 (thick Ethernet) connection.
ok watch-net
Using AUI Ethernet Interface
Lance register test -- succeeded
Internal loopback test -- succeeded
External loopback test -- Lost Carrier (transceiver cable
problem?) send failed
Using TP Ethernet Interface
Lance register test -- succeeded
Internal loopback test -- succeeded
External loopback test -- succeeded
Looking for Ethernet packets.
’.’ is a good packet. "X" is a bad packet.
Type any key to stop.
