SYNOPSIS

11       bus [-d module] [-m module] [-f configuration_file]

DESCRIPTION

14       LE  Service  consists  of three components: LAN Emulation Configuration
15       Server (lecs(8)), LAN Emulation Server (les) and Broadcast and  Unknown
16       Server (bus).
17
18       Les  performs  the  control coordination function for the emulated LAN.
19       LE clients register MAC addresses and/or route descriptors they  repre‐
20       sent  to  les,  and  later  query  it  when  they  want  to resolve MAC
21       addresses/route descriptors into ATM addresses. Other LE  control  mes‐
22       sages which are to be distributed to every client in ELAN are also sent
23       to les. Les forwards these messages using Control Distribute VCC  which
24       it has set up to every client in ELAN.
25
26       Bus  handles  data  sent  by  clients  to  broadcast  and multicast MAC
27       addresses and some of the data directed to unicast addresses. LE Client
28       has  a possibility to send data directed to some unicast address to the
29       bus before target's ATM address has been resolved and the  Data  Direct
30       VCC has been established.
31
32       Configuration file example for les and bus:
33
34         [main]
35         memdebug=True
36         debug=True
37         [load]
38         #memdebug=True
39         #debug=True
40         [conn]
41         debug=True
42         #S1, LE Server's ATM address
43         #S1=:47:00:23:00:00:00:03:00:00:01:00:02:01:00:20:ea:00:05:aa:00
44         S1=:47:00:23:00:00:00:03:03:00:01:00:02:01:00:20:ea:00:0a:e9:01
45         #S2, LAN Type
46         S2="802.3"
47         #S3, Maximum Frame Size
48         S3=1516
49         #S4, Join Timeout, s
50         S4=15
51         #S5, Maximum Frame Age, s
52         S5=6
53         #S6, BUS Atm address
54         S6=:47:00:23:00:00:00:03:03:00:01:00:02:01:00:20:ea:00:0a:e9:02 #viulu
55         #S6=0,0,170
56         #ELANNAME="asdf"
57
58       The  configuration file contains each modules name in brackets followed
59       by variable definitions for that module. The definitions  are  of  form
60       variable=value,  where  value  can  be either an integer, a truth value
61       (True/False), a string enclosed in double quotes ("string") or  an  ATM
62       address  in  hexadecimal  format.  Variables  that  can  be set are the
63       debug/memdebug for each module and variables S1-S6  as  defined  in  LE
64       specification.
65
66       S1=Address of the LES. This address is used in ATM
67          signalling.
68       S2=Type of the emulated LAN. Valid values is "802.3".
69       S3=Maximum frame size. Valid value is 1516.
70       S4=Join Timeout. Time in seconds which LES waits for
71          LE_JOIN_REQUEST before tearing down a connection.
72       S5=Maximum frame Age. Currently not used.
73       S6=Address of the BUS. This address is used in ATM signalling.
74       ELANNAME= Name of the emulated LAN
75
76       SIGHUP  causes  restart  of  the server. All resources are released and
77       server is started. SIGUSR1 causes  the  server  to  dump  its  internal
78       state. SIGUSR2 shuts down the server (hopefully) gracefully.

OPTIONS

81       -d module
82              Set debugging messages on for a module. "All" sets debug‐
83              ging on for all modules.
84
85       -m module
86              Set memory debugging messages on for a module. "All" sets
87              debugging on for all modules.
88
89       -f configuration_file
90              Use   the   specified   configuration   file  instead  of
91              .lanevars.
92

FILES

BUGS

97       Servers don't establish point-to-multipoint  connections  to  LE
98       clients  as  the  specification states, which means that some LE
99       clients won't work with these servers.
100
101       Supports only IEEE 802.3 / Ethernet type of ELANs.
102
103       This manual page is confusing.
