ATM Addresses. The LECS uses LEC Media Access Control (MAC)
addresses (also known as Ethernet addresses) to determine ELAN
assignment. If you do not want to assign a MAC address to each and every
device, a default ELAN can be created.
For example, the first screen from the Emulated LAN definitions
submenu (via the Main and LAN Emulation menus) shows the first sixteen
(of 64) ELANs.
ELAN Number corresponds to the LEC number. ELAN Name is the name
of the ELAN itself which is retrieved from the LECS during a configuration
request. ELAN #1 is Client #1 with the ATM address of: [NET Prefix] [Base
MAC Address] [Selector #01].
For instance, ELAN Number #1 is identified by “Default Elan” and is
“Operational.”
The following pages provide specific information which directly correlates the
Omega menus with LAN Emulation.
Note that a more complete discussion of Emulated LANs including such
information as address configuration and resolution, components, and
topography is contained in Appendix B — LANE.
