NAME
       atmelan - Configures LAN-Emulation clients as network interfaces.

SYNOPSIS
       /usr/sbin/atmelan command arguments

OPTIONS
       This section is organized by the tasks you can perform with the atmelan
       command.	 Each task subsection provides the atmelan command syntax  and
       the arguments to use to complete the tasks.

   Creating a LAN-Emulation Client
       Syntax:

       /usr/sbin/atmelan     create    driver=name    [type=type]    [mtu=mtu]
       [name=elan_name]

       [lecs=addr [,addr, addr, addr] | les=addr]

       [unit=unit_number | elan=unit_number]

       Creates a new LAN-Emulation Client (LEC) and configures it as a network
       interface.   If no additional arguments are specified, the defaults are
       802.3 type and an MTU of 1516 bytes.  Specifies the physical  interface
       with which to associate the new LEC.  Specifies the interface type. The
       following types are supported: Ethernet/802.3.  Specifies  the  message
       transfer	 unit (MTU) size. The following MTU sizes are supported: 1516,
       4544, 9234, and 18190.  When specified with the name option,  the  emu‐
       lated  LAN  must already be configured on the ATM switch to support the
       specified MTU size.  If it is not  configured  for  the	specified  MTU
       size,  the  request is ignored.	Specifies the name of the emulated LAN
       to join.	 The emulated LAN name must already be configured on  the  ATM
       switch.	If the name is not configured on the ATM switch, the LEC joins
       the default emulated LAN.

					    Note

	      You can join an emulated LAN on a	 switch	 only  once  for  each
	      adapter;	do not join the same elan multiple times from the same
	      adapter.	If you want to join the same emulated LAN on the  same
	      switch,  you  must install another adapter and join the emulated
	      LAN from it.  Specifies that the LEC connect to  the  LAN-Emula‐
	      tion Configuration Server (LECS) at the ATM address specified by
	      the addr arguments for the emulated LAN configuration.  You  can
	      specify  up to 4 addresses. The LEC tries the addresses in order
	      until a successful configuration	has  been  completed.  If  all
	      addresses	 fail,	the  “well  known address” is tried before the
	      process begins again.

	      If no lecs option is specified (default), the  LEC  connects  to
	      the LECS at the “well known address”.

	      Do  not use the lecs option with the les option.	Specifies that
	      the LEC go directly to the LAN-Emulation Server (LES) at the ATM
	      address  specified by addr argument and bypass the configuration
	      phase.

	      If this argument is not specified, the LEC contacts a LAN-Emula‐
	      tion Configuration Server (LECS) to obtain a LES address.

	      Do not use the les option with the lecs option.  Specifies a LEC
	      interface unit number.  Specifies an ELAN unit number.

       For example, to create an emulated LAN interface using  Ethernet	 frame
       format  and Fiber Distributed Data Interface (FDDI) frame sizes, enter:
       # atmelan create driver=lta0 mtu=4544

       To create an emulated LAN interface  that  bypasses  the	 configuration
       phase  and  directly  contacts  a  LAN-Emulation Server (LES), enter: #
       atmelan create les=LES_A

       The ATM address is an alias that is in the /etc/atmhosts file.

   Detaching a LEC Interface from an ATM Network
       Syntax:

       /usr/sbin/atmelan detach

       unit=unit_number | elan=unit_number

       Detaches a LEC interface specified by either  unit  or  elan  arguments
       from  an	 ATM  network.	 Specifies  a  LEC interface unit number.  The
       unit_number is obtained by the netstat -i command.  Specifies  an  ELAN
       unit number.  The unit_number is obtained by the netstat -i command.

   Attaching a LEC Interface to an ATM Network
       Syntax:

       /usr/sbin/atmelan attach driver=name

       unit=unit_number | elan=unit_number

       [lecs=addr [,addr, addr, addr] | les=addr]

       [name=elan_name] [type=type] [mtu=mtu]

       Attaches the specified, previously detached LEC network interface to an
       ATM network.  After the LEC interface is attached, issue	 the  ifconfig
       elanx  up  command  to configure the interface.	Specifies the physical
       interface with which to associate the LEC.  Specifies a	LEC  interface
       unit  number.   This  is	 the unit number that was previously detached.
       Specifies an ELAN unit number.  This is the unit number that was previ‐
       ously  detached.	  Specifies  that the LEC connect to the LAN-Emulation
       Configuration Server (LECS) at the ATM address specified	 by  the  addr
       arguments  for the emulated LAN configuration.  You can specify up to 4
       addresses. The LEC tries the addresses in order until a successful con‐
       figuration  has	been completed. If all addresses fail, the “well known
       address” is tried before the process begins again.

	      If no lecs option is specified (default), the  LEC  connects  to
	      the LECS at the “well known address”.

	      Do  not use the lecs option with the les option.	Specifies that
	      the LEC go directly to the LAN-Emulation Server (LES) at the ATM
	      address  specified by addr argument and bypass the configuration
	      phase.

	      If this argument is not specified, the LEC contacts a LAN-Emula‐
	      tion Configuration Server (LECS) to obtain a LES address.

	      Do  not  use the les option with the lecs option.	 Specifies the
	      name of the emulated LAN to join.	 The emulated  LAN  name  must
	      already  be  configured  on  the ATM switch.  If the name is not
	      configured on the ATM switch, the LEC joins the default emulated
	      LAN.  Specifies the interface type. The following types are sup‐
	      ported: Ethernet/802.3.  Specifies  the  message	transfer  unit
	      (MTU)  size.  The following MTU sizes are supported: 1516, 4544,
	      9234, and 18190.	When specified with the name option, the  emu‐
	      lated  LAN  must already be configured on the ATM switch to sup‐
	      port the specified MTU size.  If it is not  configured  for  the
	      specified MTU size, the request is ignored.

   Displaying State and Counters for an LEC Interface
       Syntax:

       /usr/sbin/atmelan show | status [unit=unit_number]

       Shows the state and counters for a LEC interface.  If no unit number is
       specified, information for LEC unit 0 (elan0) is displayed.  Shows  the
       state  and  counters  for a LEC interface.  If no unit number is speci‐
       fied, information for LEC unit 0 (elan0) is displayed.  Specifies a LEC
       interface  unit	number, if you want to display LEC information for LEC
       unit numbers other than unit 0 (elan0).	The unit_number is obtained by
       the netstat -i command.	For example, unit 0 is elan0, unit 1 is elan1,
       and so on.

DESCRIPTION
       The atmelan command creates and configures LAN-Emulation Clients	 (LEC)
       as  network  interfaces.	 The first interface created appears as elan0,
       the second as elan1, and so on.	The  atmelan  command  can  also  show
       counters, parameters, and the state of each LEC.
