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_ATM Asynchronous Transfer Mode IFM_CARP Common Address Redundancy Protocol IFM_ETHER Ethernet 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 option. Additional names are acceptable aliases for the media type or option.

COMMON MEDIA TYPES AND OPTIONS

The following media types are shared by all link types: IFM_AUTO Autoselect the best media. [autoselect, auto] IFM_MANUAL Jumper or switch on device selects media. [manual] IFM_NONE Deselect all media. [none] The following media options are shared by all link types: IFM_FDX Place the device into full-duplex mode.
