8.3. Interface Control Scripts
/sbin/ifup, that call on control scripts located in the
ifdowninterface scripts are symbolic links to scripts in the
/sbin/directory. When either of these scripts are called, they require the value of the interface to be specified, such as:
ifdowninterface scripts are the only scripts that the user should use to bring up and take down network interfaces.
/etc/sysconfig/network-scripts/network-functions. Refer to Section 8.4, “Network Function Files” for more information.
ifup-aliases— Configures IP aliases from interface configuration files when more than one IP address is associated with an interface.
ifdown-ippp— Brings ISDN interfaces up and down.
ifdown-ipsec— Brings IPsec interfaces up and down.
ifdown-ipv6— Brings IPv6 interfaces up and down.
ifup-ipx— Brings up an IPX interface.

service network <action>
