2p›F 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, “Switch Administration” for information about how to reach switches not directly connected to the Ethernet network.

Q• Physically connect your end nodes and edge devices to the SmartCell ZX-250 ports.

–•Configure the ATM interface or adapter for all end nodes and edge devices. Typically, configuration

consists of specifying LAN Emulation as the protocol, 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 SmartCell ZX-250 automatic addressing scheme for LANE, see Section 3.2.1.

••As each end device registers with the LES and BUS, messages are sent to the event log of the SmartCell ZX-250 containing the LECS. You can check connectivity by pinging between end nodes.

2p›F If configured devices fail to join the ELAN, see Chapter 4, Section 4.2.2, “UNI Routes.” Also, see Chapter 5, Section 5.2, “Troubleshooting LAN Emulation.”

Your ELAN is now operational. Additional ELANs can be created in the same way. See Chapter 4, “Switch Administration,” for information about SmartCell ZX-250 switch operations and maintenance.

2p›F While it is possible for a single ELAN on the SmartCell ZX-250 switch to support multiple subnets, in general, switch performance is best (and management easiest) when the “One-subnet-per-ELAN” rule is observed.
