IFMEDIA(4)                 BSD Programmer's Manual                  IFMEDIA(4)

NAME

     ifmedia - network interface media settings

SYNOPSIS

     #include <sys/socket.h>
     #include <net/if.h>
     #include <net/if_media.h>

DESCRIPTION

     The ifmedia interface provides a consistent method for querying and set-
     ting network interface media and media options. The media is typically
     set using the ifconfig(8) command.

     There are currently four link types supported by ifmedia:
           IFM_ETHER      Ethernet
           IFM_TOKEN      Token Ring
           IFM_FDDI       FDDI
           IFM_IEEE80211  IEEE802.11 Wireless LAN

     The following sections describe the possible media settings for each link
     type. Not all of these are supported by every device; refer to your
     device's manual page for more information.

     The lists below provide the possible names of each media type or option.
     The first name in the list is the canonical name of the media type or op-
     tion. Additional names are acceptable aliases for the media type or op-
     tion.

COMMON MEDIA TYPES AND OPTIONS

     The following media types are shared by all link types:
           IFM_AUTO    Autoselect the best media. [autoselect, auto]

     The following media options are shared by all link types:

                      has meaning if the device is normally not full-duplex.

           IFM_HDX    Place the device into half-duplex mode. This option only
                      has meaning if the device is normally not half-duplex.

HISTORY

     The ifmedia interface first appeared in The implementation that appeared
     in NetBSD 1.3 was written by Jonathan Stone and Jason R. Thorpe to be
     compatible with the BSDI API. It has since gone through several revisions
     which have extended the API while maintaining backwards compatibility
     with the original API.

     Support for the IEEE802.11 Wireless LAN link type was added in
     NetBSD 1.5.

     Host AP mode was added in OpenBSD 3.1.
