.SH DESCRIPTION
|
|
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.
|
|
.PP
|
|
LAN Emulation client code is divided into two parts: user space
|
|
application LAN Emulation Demon called (LED) \fBzeppelin(8)\fP, and the
|
|
kernel component. \fBZeppelin\fP 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.
|
|
.PP
|
|
Linux LEC supports only Ethernet type of emulated LAN.
|
|
.PP
|
|
\fBSIGHUP\fP causes restart of the LEC. All resources are
|
|
released and \fBzeppelin\fP is started.
|
|
.SH OPTIONS
|
|
.IP \fB\-c\ \fILECS_address\fP
|
|
ATM address of \fBlecs(8)\fP (Lan Emulation Configuration Server), if not
|
|
set, Well-Known server address is used.
|
|
.IP \fB\-s\ \fILES_address\fP
|
|
ATM address of \fBles(8)\fP (Lan Emulation Server), can be used in
|
|
bypassing configuration phase in joining emulated Lan i.e \fBlecs\fP address
|
|
is not used.
|
|
.IP \fB\-e\ \fIesi\fP
|
|
Mac address to use when communicating in Emulated LAN. E.g. 00:20:22:23:04:05 .
|
|
.IP \fB\-n\ \fIVLAN_name\fP
|
|
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.
|
|
.IP \fB\-m\ \fImesg_mask\fP
|
|
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 messages.
|
|
.IP \fB\-l\ \fIlisten_address\ |\ selector\fP
|
|
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.
|
|
.IP \fB\-i\ \fIinterface_number\fP
|
|
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 <linux/atmlec.h>.
|
|
.IP \fB\-I\ \fIphysical_interface_number\fP
|
|
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.
|
|
.IP \fB\-t\ \fIMTU\fP
|
|
The MTU of ELAN to join. You need to also use \fBifconfig(8)\fP to
|
|
set the MTU of the LANE interface.
|
|
.IP \fB\-1\fP
|
|
Run as LANEv1 client. This is the default.
|
|
.IP \fB\-2\fP
|
|
Run as LANEv2 client. This is required by MPOA.
|
|
.IP \fB\-p\fP
|
|
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.
|
|
.IP \fB\-F\ \fIlogfile\fP
|
|
Instead of writing debug messages to \fBstderr\fP, write the messages
|
|
to the file \fBlogfile\fP. Use \fBsyslog\fP as the file name to use
|
|
the \fBsyslog(3)\fP facility.
|
|
.IP \fB\-f\ \fIFore\ specific\ name\fP
|
|
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\'.
|
|
.SH TOKEN RING CONSIDERATIONS
|
|
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.
|
|
