Diagnostic Software

This appendix provides an overview of the SunVTS diagnostic application and instructions for updating the SunVTS software to recognize the Sun Blade T6320 XAUI Pass-Through Fabric Expansion Module. This appendix contains the following sections:

SunVTS Diagnostic Software

The SunVTS software executes multiple diagnostic hardware tests from a single user interface. SunVTS 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 SunVTS nettest diagnostic can be used to test all of the networking interfaces on the system, including the interfaces on the FEM.

To use the nettest diagnostic, you must have the SunVTS software installed on your system. Use SunVTS 6.4 Patch Set 3 or later. You will need to update the SunVTS configuration to recognize the FEM. Refer to the SunVTS documentation in TABLE B-1.

Using the SunVTS xnetlbtest

The xnetlbtest provides functional test coverage of the network products based on Neptune Ethernet chip/core. Refer to the SunVTS 6.4 Test Reference Manual for SPARC Platforms, for complete xnetlbltest information.

xnetlbtest Test Requirements

The NEM has an internal loopback path built in. You do not need an loopback connector. You must have the Ethernet card (the FEM) and the device driver installed. Intervention mode is enabled before running xnetlbtest. xnetlbtest cannot run and does not appear in the GUI if the network interface is connected to a live network. xnetlbtest also requires that the Ethernet device be configured offline before running the test. Use the ifconfig(1M) command to bring the Ethernet device down before running xnetlbtest. Enter the following commands to bring the interface down: 


# ifconfig nxge0 down 
# ifconfig nxge0 unplumb

Where nxge0 is the 10GbE port on your server module.
