vifconfig(1M)                                                 vifconfig(1M)

NAME
     vifconfig - configure virtual interface parameters

SYNOPSIS
     vifconfig interface [command addr [netmask]]

DESCRIPTION
     A virtual interface in this context is simply an additional IP address
     associated with the physical interface. This additional IP address can
     be viewed as an alias to the IP address normally associated with the
     physical interface. vifconfig is intended for configuring and unconfi-
     guring virtual interfaces. Used without options, vifconfig displays
     the current configuration for a network interface. The following com-
     mands can be used with vifconfig.

     The alias command creates a virtual interface with the IP address
     addr. If the netmask parameter is supplied, it becomes the netmask of
     the virtual interface, otherwise the netmask of the real interface is
     used.

     The delete command removes the virtual interface with corresponding
     addr IP address. The netmask parameter is ignored if it is supplied.

EXAMPLES
     vifconfig lce0 alias 139.22.11.10 generates an IP alias for the net-
     work interface lce0 with IP address 139.22.11.10 and default netmask.

     vifconfig lce0 alias 139.22.11.11 0xffff0000 generates an IP alias for
     the lce0 network interface with IP address 139.22.11.11 and netmask
     255.255.0.0.

     vifconfig lce0 displays the configuration for the network interface
     lce0.

          lce0: flags=23<UP,BROADCAST,NOTRAILERS>
          inet 139.22.11.7 netmask ffff0000 broadcast 139.22.11.255
          alias 139.22.11.10 netmask ffff0000
          alias 139.22.11.11 netmask fffffc000

     vifconfig lce0 delete 139.22.11.10 removes the virtual interface asso-
     ciated with the given IP address and thus removes the IP alias for the
     lce0 network interface.

NOTE
     vifconfig requires that the package SIppp (Point-to-Point protocol) be
     installed.
