zeppelin(8)

NAME
zeppelin - ATM LAN Emulation client demon (LED) Zeppelin

SYNOPSIS
zeppelin [-c LECS_address]| [-s LES_address] [-e esi] [-n VLAN_name] [-m mesg_mask] [-i interface_number] [-q qos_spec]

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.

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.

OPTIONS

-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 messages.

-l listen_address
    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.

-i interface_number
    Linux LEC supports up to 4 network interfaces. This number tells zeppelin to which of these to attach. Network interfaces are numbered from "lec0" to "lec3".

-i qos_spec
    Set the specified quality of service (see qos(7) for the syntax) for outgoing calls. UBR at link speed is used by default.

BUGS
Supports only IEEE 802.3 / Ethernet type of ELANs.

John Bonham died 1980 and Led Zeppelin broke.
