Novell Documentation: Novell Internet Access Server 4.1 - Configuring a Logical Adapter Board for ATM LEC

Configuring a Logical Adapter Board for ATM LEC

Before you begin, you must configure a physical ATM board as described in Configuring a LAN or WAN Board.

If you configure ATM LEC before configuring the physical adapter board, the LEC software will not load. ATM LEC requires an ATM adapter to be loaded and connected to an ATM switch prior to configuring the logical adapter board.

To configure a logical adapter board, complete the following steps:

NOTE: Refer to Table 1 for LAN Emulation parameter descriptions.

Load NIASCFG, then select the following parameter path:

Select Configure NIAS > Protocols and Routing > Boards

Do one of the following:

If you are configuring a new board, press Ins to display the list of available drivers.

Select ATMELEC for Ethernet emulation.

Select ATMTRLEC for token ring emulation.

If you are changing an existing board configuration, you must delete the board configuration and return to the beginning of this step to add a new board.

Select Board Name and enter a unique name.

Select ATM HSM Board Name and enter the name of the ATM HSM^TM (Hardware Specific Module^TM ) board. Multiple emulated LANs can share the same physical ATM adapter. Input in this field is required.

Select ELAN Name and specify the name of the emulated LAN. This name, if specified, must match the LES (LAN Emulation Server) name. If no name is specified the LECS (LAN Emulation Configuration Server) will determine the default. Use double quotation marks if the name contains lowercase letters (for example, \elan1\.).

Select Node Override and specify a node address to override the default if it has already been used for another emulated LAN.

Select LECS and specify the ATM address of the LECS.

Select LES and specify the address of the LES.

Select LSB (canonical) for a token ring LEC.

The default is noncanonical Most Significant Bit (MSB) mode.

Select Comment and enter a descriptive comment, if desired.

Select Board Status and indicate whether the board is loaded.

Enabled ---Indicates whether the board is loaded.

Disabled ---indicates that no driver load lines or protocol bind commands are created for the board.

Force ---Loads all LAN driver frame types.

Press Esc to return to the Internetworking Configuration menu; save your changes when prompted.

LAN Emulation Command Parameters

Table 1 describes the parameters used for ATM LEC board configuration.

Table 1. LAN Emulation Command Parameters

Parameter Name	Description
NAME	Logical board to which the protocol stacks can bind.
ELAN	The name of the emulated LAN (ELAN) to which you want this LAN port to join. This parameter is sent in a LAN Emulation Configuration Server (LECS) configuration request to obtain other parameter values associated with the ELAN from the LECS. If this parameter is not specified and the LECS address is specified in the load line, then the LECS configuration request will contain a NULL value for the ELAN. This allows the LECS to optionally assign the LAN Emulation Client (LEC) to a default ELAN and supply the default ELAN's configuration parameters to the LEC. Place the ELAN name in double quotation marks if the name contains lowercase letters (for example, ELAN NAME: \elan1\.).
NODE	The 6-byte MAC address for the ELAN port. If this parameter is not specified, the primary End Station Identifier (ESI) value (registered by the ATM adapter) is chosen as the MAC address, unless it has already been assigned to another instance of the ELAN. The NODE value should be unique within the ELAN. Otherwise, the LAN Emulation Server (LES) rejects the address and the LEC is terminated. The NODE value should not have the multicast bit on and should be a local address. Otherwise, the LEC rejects the address and is terminated.
LECS	Full 20-byte address of the LAN Emulation Configuration Server (LECS). The format for this address is 20 bytes with no separators. If the LECS is connected to the same switch as the LEC, only the last 7 bytes of the LECS address must be entered. This parameter is optional. If neither the LES nor LECS address is specified, by default, the LEC tries to access the LECS by using its well-known unicast address.
LES	Full 20-byte address of the LAN Emulation Server (LES). The format for the address is 20 bytes with no separators. If the LES is connected to the same switch as the LEC, only the last 7 bytes of the LES address must be entered. This parameter is optional.
LSB	This parameter is required only for token ring LEC when the LEC needs to handle the MAC address in the Least Significant Bit (LSB) mode (canonical mode). If this parameter is not specified, the LEC uses the default, the Most Significant Bit (MSB) mode.
ATMBOARD	Name of the ATM interface (up to 17 bytes long) that the ELAN uses. If this parameter is not specified, the first available ATM board is chosen. To avoid having an undesired board chosen, this parameter should be specified when multiple ATM boards are present.
