Using the SunVTS netlbtest

You must have the Ethernet card and the device driver installed, a loopback connector in place, and Intervention mode enabled before running netlbtest. netlbtest cannot run if the network interface is connected to a live network, and 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 netlbtest.

▼To Use the netlbtest

1.Ensure that the SunVTS software and the nxge driver are installed on your system.

2.Plug in a loopback cable.

3.Unplumb the interface from the system, using the ifconfig command:

#ifconfig nxgeinstance down

#ifconfig nxgeinstance unplumb

Where instance is the instance number of the interface.

Refer to SunVTS documentation for instructions on how to run netlbtest.
