SunVTS Diagnostic Software

The SunVTS software executes multiple diagnostic hardwaretests from a single user
interface and is used to verify the configuration and functionality of most hardware
controllers and devices. The SunVTS software operates primarily from a graphical
user interface, enabling test parameters to be set quickly and easily while a
diagnostic test operation is being performed.
The nettest and the netlbtest check all the networking interfaces on a system,
including the Sun GigaSwift Ethernet adapter.Refer to the SunVTS User’s Guide for
more information on how to run the nettest diagnostic test.
Note – Touse the nettest or netlbtest diagnostic, you must have the SunVTS
software installed on your system. Refer to the Solaris Sun Hardware Platform Guide,
which was shipped with the Solaris Supplement CD, for instructions on how to install
the SunVTS software.
