NAME
       ifcfg - common elements of network interface configuration

SYNOPSIS
       /etc/sysconfig/network/ifcfg-*

VARIABLES
       The  following is a list of variables that can be put in the configura-
       tion file, with an example in parentheses.  * marks the  default.   For
       the meaning of suffix, see the section Multiple addresses.

       STARTMODE {manual*|auto|hotplug|ifplugd|nfsroot|off}
              Choose when the interface should be set up.
              manual
                     Interface  will  be  set  up  if  ifup is called manually
                     (without option boot or hotplug)
              auto
                     Interface will be set up as soon as it is available  (and
                     service network was started). This either happens at boot
                     time when network is  starting  or  via  hotplug  when  a
                     interface  is  added to the system (by adding a device or
                     loading a driver). To be backward  compliant  onboot,  on
                     and boot are aliases for auto.
              hotplug
                     This  mode  is  nearly  the same as auto.  The difference
                     between auto and hotplug is that the latter does not make
                     rcnetwork fail if the interface cannot be brought up.
              ifplugd
                     The interface will be controlled from ifplugd. At initial
                     ifup only ifplugd will be  started  for  this  interface.
                     Then  if ifplugd detects a link if calls ifup again which
                     finally  sets  the  interface  up.  See   also   variable
                     IFPLUGD_PRIORITY below.
              nfsroot
                     Nearly like auto, but interfaces with this startmode will
                     never be shut down via rcnetwork  stop.   ifdown  <inter-
                     face>  still works. Use this when you use a root filesys-
                     tem via network.
              off
                     Will never be activated.

       IFPLUGD_PRIORITY
              If  there  multiple  interfaces  have  STARTMODE=ifplugd  and  a
              nonzero  priority,  only  one  of them will be set up at a time.
              Every time one of these interfaces is (un)plugged the  interface
              with  highest  priority  (and  plugged  cable)  will  be set up.
              Default is IFPLUGD_PRIORITY='0' causing set up as when the cable
              is  plugged.  Note: This is not supported for e.g. bridge inter-
              faces or bridge ports.

       BOOTPROTO {static*|dhcp|dhcp4|dhcp6|autoip|dhcp+autoip|6to4|none|ibft}
              Setup protocol.  If  this  variable  is  empty  or  missing,  it
              defaults to static.
              static
                     A  fixed  addresses specified in IPADDR and related vari-
                     ables  and  static  routing  as  defined  in  routes  and
                     ifroute-<interface name> files is configured.
              dhcp4 dhcp6 dhcp
                     A DHCPv4, DHCPv6 or both clients are started to configure
                     the interface. The setup is considered  successful,  when
                     at  least one dhcp client configures the interface. Addi-
                     tionally  to  the  dhcp   client   configuration,   fixed
                     addresses and routes may also be specified.
                     Note:
                     Static  routes  without  explicit  interfaces  will  also
                     replace routes to the same destination (network)  config-
                     ured by dhcp clients on any interface!
                     Static  routes  with explicit interface will also replace
                     routes to the same destination  (network)  configured  by
                     dhcp clients on this interface.
              autoip dhcp+autoip
                     may  be used for a IPv6 zeroconf setup or as fall back to
                     autoip if dhcp fails.
              6to4
                     to set up IPv6 tunnel interfaces running  in  the  "6to4"
                     mode.
                     See also ifcfg-tunnel(5) manual page.
              none
                     For bonding slaves and bridge ports to skip the interface
                     configuration.   It  is  also  recommended  (instead   of
                     static)  for interfaces configured with STARTMODE=nfsroot
                     (for nfs- and iscsi-root installation), where  the  setup
                     is done in the initrd and inconsistencies could break it.
              ibft
                     For interfaces with  iSCSI  Boot  Firmware  Table  (iBFT)
                     firmware, defined in ACPI 3.0b specification, intended to
                     use together with STARTMODE=nfsroot.  Causes  reading  of
                     the  iBFT settings (/sys/firmware/ibft) for the interface
                     and override the BOOTPROTO  setting  internally  to  dhcp
                     when  the  origin flag is set to IpPrefixOriginDdhcp (3),
                     otherwise to none.

       IPADDR[suffix] {IPv4|IPv6}[/PREFIXLEN]
              IP address, either IPv4 or IPv6. You may add /<prefixlength>  in
              both cases and omit NETMASK or PREFIXLEN.  If you need more then
              one IP address use this variable multiple times  with  different
              suffixes  added.  See  section  Multiple  addresses below. If no
              address is configured the interface will just be activated (UP).

       PREFIXLEN[suffix]
              Number of bits in IPADDR that form the network address. Alterna-
              tively add a prefix-length to IPADDR or use NETMASK.   PREFIXLEN
              is  preferred  over NETMASK.  but highest priority has a prefix-
              length added to the IP address in the variable IPADDR.

       NETMASK[suffix]
              Network mask. Alternatively add a prefix-length to IPADDR or use
              PREFIXLEN.  This variable is ignored if a prefix-length is spec-
              ified.

       BROADCAST[suffix]
              Network broadcast. If you omit the broadcast address, it will be
              calculated  from  netmask  or  prefix-length. You can affect the
              calculation with the variable DEFAULT_BROADCAST in  /etc/syscon-
              fig/network/config.  See the description there.

       REMOTE_IPADDR[suffix]
              The remote IP address of a point to point  connection

       LABEL[suffix]
              Each address may be tagged with a label  string.   In  order  to
              preserve compatibility  with Linux-2.0 net aliases, this  string
              must coincide with the name of the device or  must  be  prefixed
              with the device name followed by colon.  This may be useful with
              Multiple addresses (see below).

       SCOPE[suffix]
              The  scope  of the area where this address is valid.  The avail-
              able scopes are listed in file /etc/iproute2/rt_scopes.   Prede-
              fined scope values are:
                      global - the address is globally valid.

                      site - (IPv6 only) the address is site local, i.e. it is
                      valid inside this site.

                      link - the address is link local, i.e. it is valid  only
                      on this device.

                      host - the address is valid only inside this host.

       MTU    Set the maximum transfer unit (MTU) for this interface.

       IP_OPTIONS[suffix]
              Any  other  option  you  may  want to give to the ip add add ...
              command. This string is appended to the command.

       LLADDR Set an individual link layer address (MAC address).

       LINK_OPTIONS
              Here you may add any option valid with ip link set up ...

       INTERFACETYPE
              Sometimes ifup cannot determine the interface type properly.  In
              this cases you may specify it in this variable.

       ETHTOOL_OPTIONS
              If  this  variable is not empty ifup will call ethtool with this
              options.  See the ethtool (8) manual page for available options.
              If  the option string starts with a '-' (e.g. '-K iface rx on'),
              then the second word in the string will  be  replaced  with  the
              current interface name.  Otherwise (e.g. 'autoneg off speed 10')
              ifup prepends '-s <interface>'.

       RUN_POLL_TCPIP {yes*|no}
              Controls running /etc/ppp/poll.tcpip when a dialup connection is
              established.

       PRE_UP_SCRIPT, POST_UP_SCRIPT, PRE_DOWN_SCRIPT and POST_DOWN_SCRIPT
              Here  you  can  hook a script (better: an executable) to perform
              individual actions before/after  the  interface  is  set  up  or
              before/after  the  interface  is  set down.  If you use relative
              filenames  ifup  will  look  for  them  in   /etc/sysconfig/net-
              work/scripts  but  you may use absolute paths as well. They were
              called scripts, because they usually are scripts,  but  you  may
              add  also  binaries here. If they are scripts, they must be made
              executable.

              These scripts will be called with nearly the same  arguments  as
              ifup.   The  only  difference  is  that  the  configuration-name
              (optional for ifup) is always set with the  name  determined  by
              getcfg. The configuration name is stored in the variable $CONFIG
              which may be used inside the ifcfg- configuration file.

              If BOOTPROTO=dhcp then the post up and pre down scripts will not
              be  executed  immediately  by  ifup/ifdown. Instead dhcpcd calls
              ifup/ifdown with a special option always after it sets,  changes
              or  removes  the  IP  address. Therefore post up scripts will be
              executed after the interface is really  up  which  may  be  much
              later  if  dhcp  did  not  get a lease immediately. And pre down
              scripts are called after  dhcp  shut  down  the  interface  (not
              before as 'pre' would indicate. This is a problem of dhcpcd).

       TUNNEL, TUNNEL_*
              Using this variable you may set up different tunnels. See ifcfg-
              tunnel (5) manual page.

       ETHERDEVICE
              Needed only for virtual LANs  (802.1q).  It  contains  the  real
              interface to use for the vlan interface. See ifcfg-vlan (5) man-
              ual page.

       BONDING_MASTER, BONDING_SLAVE_*, BONDING_OPTS, BONDING_MODULE_OPTS
              These are used to set up interface  bonding.  See  ifcfg-bonding
              (5) manual page.

GENERAL VARIABLES
       There are some general settings in the file /etc/sysconfig/network/con-
       fig.  If needed you can also set every general variable as an  individ-
       ual variable in the ifcfg-* files.

       DEFAULT_BROADCAST

       GLOBAL_POST_UP_EXEC

       GLOBAL_PRE_DOWN_EXEC

       CHECK_DUPLICATE_IP

       DEBUG

       USE_SYSLOG=

       MODIFY_RESOLV_CONF_DYNAMICALLY

       MODIFY_NAMED_CONF_DYNAMICALLY

       MODIFY_RESOLV_CONF_STATIC_DNS

       CONNECTION_SHOW_WHEN_IFSTATUS

       CONNECTION_CHECK_BEFORE_IFDOWN

       CONNECTION_CLOSE_BEFORE_IFDOWN

       CONNECTION_UMOUNT_NFS_BEFORE_IFDOWN

       CONNECTION_SEND_KILL_SIGNAL

       MANDATORY_DEVICES

       WAIT_FOR_INTERFACES

       FIREWALL

       LINKLOCAL_INTERFACES

       IFPLUGD_OPTIONS

       Please  see  the  description of these variables in /etc/sysconfig/net-
       work/config.

Multiple addresses
       You can extend the variable name IPADDR by any  string  you  like.  For
       example  IPADDR_1,  IPADDR-FOO  or  IPADDRxxx.  Use these variables for
       your IP addresses.  If you need some additional  parameters  for  these
       addresses,  then  just  add the same extension to these variable names:
       BROADCAST, NETMASK, PREFIXLEN, REMOTE_IPADDR, LABEL, SCOPE, IP_OPTIONS.

       Example:
          IPADDR_AAA=1.2.3.4
          NETMASK_AAA=255.0.0.0
          BROADCAST_AAA=1.2.3.55
          IPADDR_BBB=10.10.2.3/16
          LABEL_BBB=BBB
          and so on ...

       You do not need to set a label for any address. But then you should not
       use ifconfig any longer; go and use ip.  If you want  to  use  ifconfig
       then omit the label for your main address and set a number as label for
       every additional address.
