As a result, the LES and BUS on an ELAN use the same ATM address and
the CIP interface address may be in conflict with one of the LANE
components
′
addresses. These ATM address duplications are supported by
the IBM 8285 and also by the
The ATM Forum standard.
Note
As to the ATM address sharing of LANE servers,
The ATM Forum
standard is defined as follows:
An LES may share an ATM address with an ATM address with a BUS on
the same ELAN. An operational LES must not share an ATM address with
any LANE components other than a BUS, even if two LANE components
are co-located and share the use of a UNI. In particular, two LES for
different ELANs must not share an ATM address.

LES/BUS Parameters
The integrated LES/BUS supports Forum-Compliant LAN Emulation LES/BUS
functions with or without an external LECS. It supports all higher layer
protocols of Forum-Compliant LAN Emulation, such as TCP/IP, IEEE 802.2
protocols and NetWare.
To configure the LES/BUS, use the SET LAN_EMUL SERVER command with
the following parameters:
−
Server ID
Specify the designated LES/BUS identifier to issue the command. The
valid options are 1 or 2.
−
START / STOP
Start or stop the designated LES/BUS. When the command is to stop the
server, the following parameters are not needed.
−
ELAN Type
Specify the ELAN type of the designated LES/BUS. The valid options are
ETH (Ethernet LANE) or TR (token-ring LANE). When the ELAN type of
the LES/BUS is Ethernet, it always supports both Ethernet types, 802.3
and DIX/Ethernet V2; you cannot make it support only either type.
