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 componentsaddresses. 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.
