Purpose

This command configures a network interface

USAGE

OPTIONS

       -a     displays all interfaces which are currently available, even if down

       -s     display a short list

DESCRIPTION

Ifconfig is  used to configure the kernel-resident network interfaces. It is used at boot time to set up interfaces as necessary.  After that, it is usually  only needed  when debugging or when system tuning is needed.

If no arguments are given, ifconfig displays the  status  of  the  currently  active interfaces.  If a single interface argument is given, it displays the status of the given interface only; if a single  -a  argument  is  given,  it  displays the status of all interfaces, even those that are down.  Otherwise, it configures an interface.
