ifcfg - simplistic script which replaces ifconfig IP management SYNOPSIS
ifcfg [ DEVICE ] [ command ] ADDRESS [ PEER ] DESCRIPTION
This manual page documents briefly the ifcfg command. This is a simplistic script replacing one option of ifconfig , namely, IP address management. It not only adds addresses, but also carries out Duplicate Address Detection RFC-DHCP, sends unsolicited ARP to update the caches of other hosts sharing the interface, adds some con- trol routes and restarts Router Discovery when it is necessary. IFCONFIG - COMMAND SYNTAX DEVICE - it may have alias, suffix, separated by colon. command - add, delete or stop. ADDRESS - optionally followed by prefix length. peer - optional peer address for pointpoint interfaces. NOTES
This script is not suitable for use with IPv6. SEE ALSO

ifcfg-bonding - interface bonding configuration SYNOPSIS
/etc/sysconfig/network/ifcfg-bond* Bonding Interfaces To setup a bonding interface you need a configuration file ifcfg-bond<X> with the usual network settings. But you must add additional vari- ables BONDING_MASTER must be set to 'yes' to identify this interface as a bonding interface BONDING_SLAVE_<X> here you specify the interface name representing the slave network interfaces. BONDING_MODULE_OPTS contains bonding options. Here you can set interface timeouts or working modes ('mode=active-backup' for backup mode). For addi- tional information take a look into the documentation mentioned at the bottom. Note, that this options are not passed as parameters to the bonding kernel module any more, but set via sysfs interface. This variable will be renamed in the feature. BONDING_SKIP_REMOVE_WORKAROUND When set to "yes", a bonding interface will be not removed while ifdown any more to avoid problems, e.g. when some third party ker- nel module, such as Veritas 'llt' module, does not react correctly to the UNREGISTER event and does not remove its references to the bonding interface causing all network related operation to stuck. Note: the bonding options are not reverted when this option is enabled and it is required to either explicitly keep the old options and set them to their default setting on bonding configuration changes or to reboot. Example Example for a bonding interface on eth0 and eth1 using the backup mode ifcfg-bond0 STARTMODE='onboot' BOOTPROTO='static' IPADDR='' BONDING_MASTER='yes' BONDING_SLAVE_0='eth0' BONDING_SLAVE_1='eth1' BONDING_MODULE_OPTS='mode=active-backup miimon=100' Additional Information For additional and more general information take a look into /usr/src/linux/Documentation/networking/bonding.txt. Maybe you need to install the kernel sources to get this additional documentation. The configuration of routes for this kind of interface does not differ from ordinary interfaces. See man routes for details. BUGS
