Preparing the ATM adapter for LANE

Configuring the LANE Configuration Server address

About configuring the LANE Configuration Server address

For the filer to participate in an Emulated LAN, you must configure the ATM adapter with the address of the LANE Configuration Server. The LANE Client joins an Emulated LAN by first exchanging configuration information with the LANE Configuration Server. The LANE Configuration Server then supplies the client with the ATM address for the LANE Server.

Knowing the LANE Configuration Server address, the system can now determine all existing Emulated LANs, as well as the ATM address of the LANE Server. However, the LAN Type remains unknown until you configure the adapter to join the Emulated LAN, which is discussed in Configuring the ATM adapter for an Emulated LAN.

Configuring the LANE Configuration Server address

To configure the LANE Configuration Server address for your ATM adapter, complete the following steps.

Step	Action
1	Enter the following command to set the LANE Configuration Server address: atm elconfig set -lecs ATM_address \| -wellknown \| -manual -unit unit_number ATM_address is the ATM address of the LANE Configuration Server on the network. `-wellknown` indicates that the well-known ATM address will be used. `-manual` places the host in manual configuration mode; configuration information is not retrieved from the LANE Configuration Server. unit_number is the unit designator for the ATM adapter in the filer. Note You do not have to specify the unit number if only one ATM adapter is installed in a filer.
2	Enter the following command to check that the adapter is communicating with the LANE Configuration Server: `atm e`lconfig show -all
3	Study the output. If a separate line fails to appear for each configured Emulated LAN, grouped by adapter, verify that each Emulated LAN is configured properly for the ATM switch. For more information, see your switch vendor's documentation.

Step

Action

Enter the following command to set the LANE Configuration Server address:

atm elconfig set -lecs ATM_address | -wellknown | -manual 
-unit unit_number

ATM_address is the ATM address of the LANE Configuration Server on the network.

-wellknown indicates that the well-known ATM address will be used.

-manual places the host in manual configuration mode; configuration information is not retrieved from the LANE Configuration Server.

unit_number is the unit designator for the ATM adapter in the filer.

Note
You do not have to specify the unit number if only one ATM adapter is installed in a filer.

Enter the following command to check that the adapter is communicating with the LANE Configuration Server:

atm elconfig show -all

Study the output.

If a separate line fails to appear for each configured Emulated LAN, grouped by adapter, verify that each Emulated LAN is configured properly for the ATM switch. For more information, see your switch vendor's documentation.

Example of the atm elconfig set command with a well-known address

The following command sets the LANE Configuration Server address to the well-known ATM address for the adapter in slot 2:

atm elconfig set -lecs -wellknown -unit 2

Example of the atm elconfig set command without a well-known address

If the LANE Configuration Server on your network does not use the well-known address, specify the LANE Client Server ATM address in place of wellknown, as shown in the following command:

atm elconfig set -lecs 
47.0079.00.000000.0000.0000.0000.00a03e000001.00 -unit 2

Example of the atm elconfig show command

Abbreviated sample output (showing Emulated LANs available through the LANE Configuration Server for Adapter 2 only) from the atm elconfig show -all command is as follows:

Interpreting the output

Each Emulated LAN on the network should appear in the output, and the LAN Type and LANE Server ATM addresses should appear as expected. There should be a separate line for each configured Emulated LAN on the network, grouped and arranged for each ATM adapter that is installed in the filer.

An arrow to the left of an Emulated LAN signifies that the ATM adapter has been configured to operate on that Emulated LAN. For information about configuring adapters to operate on an Emulated LAN, see Adding an Emulated LAN to the ATM adapter.

The LANE Server ATM address should appear valid. If it does, you know that the ATM adapter in the filer is communicating properly with the switch. If the LANE Server ATM address is all zeros, it might mean that the cable connection is not working or something else is improperly configured at the switch.

The LANE Configuration Server ATM address should match the address that you specified earlier in Configuring the LANE Configuration Server address.
