Setting the LECS ATM Address
Some LAN Emulation Clients (LECs) determine the ATM address of their associated LES from the LAN
Emulation Configuration Server (LECS). The ATM Workgroup Switch supports these LECs with three
separate methods for establishing a connection to the LECS:
Ÿ LECS Well Known Address
Ÿ
ILMI MIB
Ÿ Fixed PVC (0.17)
LECS Well Known Address
The LEC can directly call the LECS Well Known Address, which is
47.00.79.00.00.00.00.00.00.00.00.00.00.00.A0.3E.00.00.01.00 .
For LECs that use this method of addressing, you must define the LECS unicast address to be
substituted for the Well Known Address in each ATM switch on the Call-Setup path, using the command:

set lan_emul configuration_server active_wka
39.99.99.99.99.99.99.ðð.ðð.99.99.ð1.ð4.ðð.11.8ð.95.4F.13.ðð
Notes:
1. You can define several ATM addresses for the LECS, but only one can be enabled at a time (using
the command SET LAN_EMUL CONFIGURATION_SERVER ACTIVE_WKA ).
2. In order to use this method, the LECS must be able to accept calls to the WKA. If the LECS does
not support calls to the WKA, you must use another addressing method.
ILMI MIB
The LEC can get the unicast ATM address by doing a GETNEXT on the variable atmSrvcRegATMAddress
in the ILMI MIB.
For LECs that use this method of addressing, you must define the LECS ATM address in each ATM
switch that deals with these LECs. You define the LECS ATM address with the
SET LAN_EMUL
CONFIGURATION_SERVER command, as described in the IBM 8285/8260: ATM Command Reference Guide,
SA33-0385.
Define the LECs address in each ATM switch that deals with these LECs, for example:
à

set lan_emul configuration_server inactive_wka
39.99.99.99.99.99.99.ðð.ðð.99.99.ð1.ð2.ðð.8ð.ð5.A9.92.9F.ðð
