ifup - Man Page

Examples (TL;DR)


ifup ā€” bring a network interface up

ifdown ā€” take a network interface down


ifup CONFIG [boot]
ifdown CONFIG


The ifup and ifdown commands may be used to configure (or, respec- tively, deconfigure) network interfaces based on interface definitions in the files /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-<configuration>

These scripts take one argument normally: the name of the configuration (e.g. eth0). They are called with a second argument of "boot" during the boot sequence so that devices that are not meant to be brought up on boot (ONBOOT=no, see below) can be ignored at that time.
