SYNOPSIS

9       lecs [-l listen_address] [-f configuration_file] [-d ]

DESCRIPTION

12       LE  Service  consists  of three components: LAN Emulation Configuration
13       Server (lecs), LAN Emulation Server ( les(8)) and Broadcast and Unknown
14       Server (bus(8)).
15
16       Lecs  implements  the  distribution of LECs to different emulated LANs.
17       This is done by giving different LAN Emulation Server ATM addresses  to
18       LECs. Distribution is based on lecs's configuration database and infor‐
19       mation provided by the LE client. It is not required that a lecs exists
20       for  all  emulated  LANs.  It  is possible to bypass this configuration
21       phase by directly telling ATM address of the les(8) to the LEC.
22
23       Configuration file example for lecs:
24         # Our ATM address (should be included to differentiate us from
25         # e.g. LEC)
26         # Must be before ELAN definitions

28
29         # ELAN name is inside brackets.
30         # Parameters below are for Ethernet type LE (Linux & almost all
31         # other LE clients)
32         [tut-lane1]
33         # Address of the LES
34         LES:=470023000000030300010002010020ea000ae901
35         # 802_3 or 802_5 (802_3 = Ethernet)
36         Type:=802_3
37         # 1515, 4544, 9234 or 18190 (1516= Ethernet)
38         Max_Frame:=1516
39
40         # ATM address for hosts that are guided to this ELAN.
41         # Wildcard is x or X.

56       Rules for  finding  ELAN  definitions  using  information  provided  in
57       LE_CONFIGURE_REQUEST and the configuration file are as follows:
58
59         1. Find an entry where ELAN-NAME matches exactly and an
60            ATM address of the LEC is found in ELAN definition.
61            These are to match exactly with the information given in
62            LE_CONFIGURE_REQUEST. If ELAN-NAME is found, but ATM
63            address doesn't match then reject with reason "Permission
64            denied".
65         2. Search for first ELAN which matches in type of emulated LAN,
66            maximum frame size and ATM address of the LEC.
67         3. If matching ELAN was not found, return default ELAN
68            definitions.
69         4. No match, so request is rejected with reason "No
70            Configuration".
71
72         SIGHUP restarts the server.
73

OPTIONS

75       -d     Reads  the  configuration  file,  dumps  its contents and
76              exits.
77
78       -l listen_address
79              Use the listen_address to where wait connections.
80
81       -f configuration_file
82              Use  the  specified   configuration   file   instead   of
83              .lecs_conf.
84

FILES
