IFPORT(8)                                                            IFPORT(8)




NAME

       ifport - select the transceiver type for a network interface



SYNOPSIS

       ifport interface [auto|10baseT|10base2|aui|100baseT|##]



DESCRIPTION

       Ifport  sets  the transceiver type for the specified network interface,
       for drivers that support multiple transceiver types.  If a type is  not
       specified on the command line, then the current type is displayed.  The
       type can be specified either numerically or by keyword.  The five stan-
       dard transceiver types (auto, 10baseT, 10base2, aui, and 100baseT) cor-
       respond to codes 0 to 3, for all the Linux PCMCIA network drivers.  The
       keyword match is case insensitive.

       The  network  drivers  may not reconfigure a card for a new transceiver
       type if the interface is already open.  It is  best  to  invoke  ifport
       prior to configuring the interface with ifconfig to ensure that the new
       setting takes effect immediately.

       This utility only works with a limited set of 16-bit PC  Card  drivers:
       3c589_cs, nmclan_cs, pcnet_cs, smc91c92_cs, and xirc2ps_cs.  If invoked
       for other drivers, ifport may report  bogus  transceiver  settings,  or
       report ``Operation not supported''.



DIAGNOSTICS

       ioctl: Operation not supported
              Indicates  that  this  network  device  does  not support manual
              transceiver  selection.   There  may  be  only  one  transceiver
              option,  or  the  device  may  always autodetect the appropriate
              transceiver.
