If multiple Emulated LANs (ELANs) are present, you can enter a character string in the Emulated LAN Name parameter. The LAN Emulation client uses this parameter to tell the LAN Emulation services which ELAN it wishes to join. By default, if a SunATM LAN Emulation client does not specify an ELAN name, it tells the services to assign it to the default (or only) ELAN.
If you have multiple LAN Emulation instances configured on a physical interface, only one instance can join the default (unspecified) ELAN. You must specify an ELAN name for all other instances.
