IP Over ATM and LANE Creating an Emulated LAN

Note When you create a client, it automatically finds the LECS address using ILMI.

Note The command add laneclient always prompts you with a subnet mask that is appropriate for the IP address. However, if necessary, you can change the subnet mask to correspond to the strategy employed within your networks.

As the local client joins the ELAN, the following messages are sent to the Event Log (see Chapter 9, "Troubleshooting." Section 9.5):

NOTICE - 'ZLESSRV' LES Join 39:00:00:00:00:00:00:00:00:00:14:41:80:00:20:D4:

14:41:82:00

NOTICE - 'ZLESSRV' BUS Connect 39:00:00:00:00:00:00:00:00:00:14:41:80:00:20:D4:

14:41:82:00

Caution Never create an ELAN (or ELAN client) with the same subnet as the ATM

SmartSwitch’s Ethernet port.

4.Enter the show client command verify that the client is operational.

Note While creating an ELAN client for the switch is not absolutely necessary, it does provide management connectivity with the switch over its ATM ports (instead of the Ethernet port). See Chapter 4, "Routing." Section 4.5 for information about how to reach switches not directly connected to the Ethernet network.

5.Physically connect your end nodes and edge devices to the ATM SmartSwitch ports.

6.Configure the ATM interface or adapter for all end nodes and edge devices. Typically, configuration consists of specifying LAN Emulation as the connection type, assigning the device an IP address that corresponds to the subnet of the switch’s client, and indicating that you want the device to either
