Provides an Forum-Compliant LAN Emulation implementation which
supports:
− Integrated LAN Emulation Server (LES)/Broadcast and Unknown Server
(BUS)
There are two instances of the LES/BUS in the 8285 ATM Control Point,
allowing up to two Emulated LANs (ELANs), either token-ring or Ethernet,
to be configure.
− Integrated LAN Emulation Client (LEC)
There are two instances of the LEC configurable in the 8285 ATM Control
Point, allowing the 8285 ATM Control Point to be accessible from up to
two ELANs, either token-ring or Ethernet.
− LAN Emulation Configuration Server (LECS)
Although the LECS function is not integrated in to the 8285 ATM Control
Point, support is provided for using an external LECS by using its
well-known address, or by getting its ATM address through the ILMI
protocol.
