There is not normally a command that a virtual infrastructure administrator should need. The tool is automatically used when you start an ESX server in troubleshooting mode; i.e. when you start only the service console Linux kernel and don’t start the VMkernel.When you are working in the service console while the VMkernel is loaded, the service console’s network interface is not called eth0, but is called vswif0 instead. This is because the service console network interface is provided via a service console portgroup on a virtual Ethernet switch. If you restart your ESX server without the VMkernel, then standard Linux drivers and network card management is used. Therefore the network interface used in troubleshooting mode is called eth0 – just like any other regular Linux box. This tool is called by starting troubleshooting mode to replicate the IP parameters assigned to vswif0 to eth0.Should you want to investigate this command, the options are:esxcfg-linuxnet –setup

–remove

-h –help

The –setup option cannot be combined with the –remove option.
