Figure 14-1 illustrates the various connections LANE provides.
Figure14-1 LANE Concept
Refer to the Guide to ATM Technology for the following background topics on LANE:
How LANE works—the operation of LANE and the function of ATM network devices in LANE
LANE components—the function of the server and client compon ents that are required for LANE
LANE virtual circuit connection (VCC) types—the role of each VCC type in establishing,
maintaining, and tearing down LANE connections
Addressing—the scheme used in automatically assigning ATM addresses to LANE compon ents
LANE examples—step-by-step process of joining an emulated LA N and building a LANE
connection from a PC

LANE Router and Switch Router Requirements

You must manually configure Q.2931 over Signaling ATM Adaptation Layer (QSAAL) and ILMI
signalling PVCs on routers and edge LAN switch routers to run LANE. However, these signalling
permanent virtual channels (PVCs) are automatically configured on the ATM switch router.
Note The Catalyst 8510 MSR and LightStream 1010 processor and port adapters can be installed in slots
9 through 13 of the Catalyst 5500 switch. In this case, no physi cal connection is required between the
ATM port adapter and the LANE card if the ATM Fabric Integration Module is used.
At least one ATM switch router is required to run LANE. For example, you cannot run LANE on routers
connected back-to-back.
LANE Configuration Tasks
Before you begin to configure LANE, you must decide whether you want to set up one or multiple
emulated LANs. If you set up multiple emulated LANs, you must also decide where the servers and
clients will be located, and whether to restrict the clients that can belong to each emulated LAN. The
procedure for configuring bridged emulated LANs is the same as for any other LAN.
