       A  LAN Emulation Client is an entity in an ATM endstation that performs
       data forwarding, address resolution and  other  control  functions.  It
       uses  the  LUNI  interface  when communicating with other components in
       emulated LANs. It provides upper protocol layers a MAC  like  interface
       similar to IEEE 802.3/Ethernet or IEEE 802.5/Token Ring LAN.

       LAN  Emulation client code is divided into two parts: user space appli-
       cation LAN Emulation Demon called (LED)  zeppelin(8),  and  the  kernel
       component. Zeppelin is responsible for control operations needed in LAN
       Emulation clienthood. It forms the necessary VCCs and receives all  the
       LE  control frames and acts accordingly. It also controls the operation
       of the LEC kernel component.

       Linux LEC supports only Ethernet type of emulated LAN.

       SIGHUP causes restart of the LEC. All resources are released  and  zep-
       pelin is started.


       -b     Run  in  background  (i.e. in a forked child process) after ini-
              tializing kernel interface.

       -c LECS_address
              ATM address of lecs(8) (Lan Emulation Configuration Server),  if
              not set, Well-Known server address is used.

       -s LES_address
              ATM  address  of  les(8)  (Lan Emulation Server), can be used in
              bypassing configuration phase in joining emulated Lan  i.e  lecs
              address is not used.

       -e esi Mac  address  to  use  when  communicating in Emulated LAN. E.g.
              00:20:22:23:04:05 .

       -n VLAN_name
              Name of the virtual LAN to which joining is requested.  This  is
              used in LE_CONFIGURE_REQUEST to LECS or LE_JOIN_RESPONSE to LES,
              if configuration phase is bypassed.

       -m mesg_mask
              Sometimes one wants to know more what is happening in LE  daemon
              e.g.  when  nothing works. This is a hexadecimal long value set-
              ting global message mask. 0 = No messages, ffff = All  messages.

       -l listen_address | selector
              Local  ATM  address that zeppelin uses as local binding point in
              signalling. Use this if you are running more than one client  or
              a  set  of LE servers. The local ATM address can be specified by
              either giving the full ATM address or the desired selector byte.

       -i interface_number
              Linux  LEC  supports  up  to 40+8 network interfaces. The inter-
              face_number tells zeppelin to which of these to attach. Ethernet
              type  network interfaces are numbered from "lec0" to "lec39" and
              Token Ring interfaces are from "lec40" to "lec47". These parame-
              ters  are  tweakable  during the kernel compile, see <linux/atm-

       -I physical_interface_number
              The physical interface this LANE client should bind to. If  your
              host  has multiple ATM network cards, you can use this option to
              choose which card this zeppelin will use.

       -t MTU The MTU of ELAN to join. You need to also use ifconfig(8) to set
              the MTU of the LANE interface.

       -1     Run as LANEv1 client. This is the default.

       -2     Run as LANEv2 client. This is required by MPOA.

       -p     Enable  proxy.  When started with this option, it is possible to
              bridge packets between ATM and Ethernet. That is,  you  can  use
              LANE  interfaces  with  normal  bridging. See the Bridging mini-
              Howto for more info.

       -F logfile
              Instead of writing debug messages to stderr, write the  messages
              to the file logfile. Use syslog as the file name to use the sys-
              log(3) facility.

       -f Fore specific name
              The LANE servers on Fore ATM switches can display a special name
              if  a  client can supply one. This name shows with command ┬┤conf
              lane les show advanced┬┤.


       A number of lec interfaces is reserved for Token Ring  ELANs  when  the
       kernel is compiled with Token Ring (CONFIG_TR) support. See the discus-
       sion about interface_number command line option above. The Linux  Token
       Ring  LANE  client  does not support bridging between legacy Token Ring
       and ATM parts of the ELAN, so using the -p option is  not  recommended.
       Token Ring support has received less testing than its Ethernet counter-
