landiag
A diagnostic program that tests LAN connections
between HP Integrity computers.
linkloop
A diagnostic program that runs link-level
loopback tests between HP Integrity systems.
linkloop uses IEEE 802.3 link-level test frames
to check physical connectivity with the LAN. This
diagnostic tool is different from the loopback
capability of landiag because it tests only the
link-level connectivity and not the transport-level
connectivity.
ping
A diagnostic program that verifies the physical
connection to a remote host and reports the
round-trip communication time between the local
and remote hosts. (Type man 1M ping for more
information.)
psidad
A utility under DUI that can help to identify
problems on the PSI/800 board/card.
rlb
A diagnostic program that tests LAN connections
to other HP Integrity computers. rlb does not test
a connection to an HP 1000 computer.
x25check
x25server
These two work in tandem. x25server runs on
the logically remote host (could be same physical
host) and echoes packets sent to it over the X.25
network by x25check.
x25stat
A nodal management command that returns
status and information from the X.25 device and
card. It provides interface status configuration
information and virtual circuit statistics.
x25upload
A command that uploads the firmware in case of
problems with the firmware on the board.
Event Logging A utility that sends informational messages
regarding network activity to the system console
or to a file.
