       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
       application  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
       zeppelin is started.


       -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
              setting global message  mask.  0  =  No  messages,  ffff  =  All

       -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
              interface_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  parameters  are  tweakable during the kernel compile, see

       -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
              syslog(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
       discussion 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 counterpart.
