•
A name for the database
•
The ATM address of the LES for the ELAN
•
A default name for the ELAN
In addition, you indicate that the LECS’s ATM address is to be computed automatically.
The default ELAN cannot be a restricted-membership ELAN. You do not need to specify the ATM or
MAC addresses of the LECs for the default ELAN.
On the Dual PHY ATM modules, you must configure redundant LESs or BUSs and a LECS, one for each
PHY.
When you configure a database with only a default unrestricted ELAN, you need not specify where the
LECs are located. That is, when you set up the LECS’s database for a single default ELAN, you need not
provide any database entries that link the ATM addresses of any clients with the ELAN name. All of the
clients are automatically assigned to a default ELAN.
Note
After you configure the LECS database, you must bind the LECS database to the major ATM interface
(ATM0) on the ATM module. For information on how to bind the database to the interface, see the
the LECS to the ATM Interface, page 17
section later on in this chapter.
To set up the LECS for a default ELAN, use the following commands beginning in global configuration
mode:

DETAILED STEPS
Command or Action
Purpose
Step 1
ATM(config)# lane
databasedatabase-name
Enters database configuration mode for the LANE database that you specify.
Step 2
ATM(lane-config-database)#
nameelan -nameserver-atm-
addressatm-address [index n ]
Binds the name of the ELAN to the ATM address of the LES in the configuration
database.
The index determines the priority. The highest priority is 0.
Enter the ATM address of the server for the specified ELAN, as noted in your LANE
worksheet and obtained in the
Displaying LANE Default Addresses, page 11
section.
You can have any number of servers per ELAN for fault tolerance. Priority is determined
by entry order. The first entry has the highest priority unless you override it with the
index number.
