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.
