IP Over ATM and LANE Creating an Emulated LAN
Caution Never create an ELAN (or ELAN client) with the same subnet as the
SmartSwitch 6500 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 5, "Routing." Section 5.5 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 SmartSwitch 6500 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
acquire the LECS address through ILMI or use the Well Known Address as the address for the
LECS. For details on the SmartSwitch 6500 automatic addressing scheme for LANE, see
Section 3.2.1.
7. As each end device registers with the LES and BUS, messages are sent to the event log of the
SmartSwitch 6500 containing the LECS. You can check connectivity by pinging between end nodes.
Note If configured devices fail to join the ELAN, see Chapter 5, "Routing." Section 5.3.
Also, see Chapter 9, "Troubleshooting."
Your ELAN is now operational. Additional ELANs can be created in the same way.
Note While it is possible for a single ELAN on the SmartSwitch 6500 switch to support
multiple subnets, in general, switch performance is best (and management easiest)
when the “One-subnet-per-ELAN” rule is observed.
