Test-all
The test-all command tests all devices in the system that have a self-test program.
Tests are executed in order, using the device tree (viewed with the show-devs
command) as reference. Disks, tapes, and CD-ROMs are not tested by test-all.
Watch-clock
This test reads a register in the NVRAM/TOD (Nonvolatile RAM/Time of Day) chip
on the main logic board and displays the result as a seconds counter. The counter
should count from 0 to 59 repeatedly until you interrupt it by pressing any key on
the keyboard.
The following screen gives you an example of a watch-clock test.
ok watch-clock
Watching the 'seconds' register of the real time clock chip.
It should be 'ticking' once a second.
Type any key to stop

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:
ok watch-net
Internal loopback test -- succeeded.
External loopback test -- Auto-selecting Ethernet cable I/F
Trying AUI
Received packet on AUI
Select cable - AUI
succeeded.
Looking for Ethernet packets.
'.' is a good packet. "X" is a bad packet.
Type any key to stop.

SPARCclassic and SPARCstation LX systems have two types of on-board Ethernet
interfaces, 10BaseT (also called twisted-pair Ethernet or TPE) and 10Base5 (also
called thick Ethernet or AUI). Only one on-board interface may be connected at a
time. The system can automatically select which interface is connected and active.
