D.1.4 watch-net, watch-aui, watch-tpe, and
watch-net-all
These tests monitor broadcast Ethernet packets on the Ethernet cable(s)
connected to the system. Good packets received by the system are indicated by
a period (.) displayed on the screen. Errors are indicated with an X and the
error description.
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.
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.
