LECS ATM Address

By default, the SunATM software attempts to obtain the LECS address using ILMI,
as specified in the LAN Emulation specification. If this is not successful, the “well-
known” ATM address, also specified by the ATM Forum, is used.

If your LECS uses a different ATM address (not the well-known address), and does
not make that address available via ILMI, specify it using this parameter. If
applicable, any of the ATM address variables described in “ATM Address Formats
and Variables” on page 34
may be used. Use variable

$prefix

, in particular.

LES ATM Address

This parameter is required if the value of the LECS Indicator parameter is

no_LECS

.

There is no “well-known” address for the LES, so an ATM address must be specified
for the LES since there is not an LECS present to provide one. This parameter is a
standard ATM address. If any of the SunATM address variables described in Section
5.3.4.3 under “ATM Address Formats and Variables” (

$prefix

in particular) are

applicable, they can be used.

Emulated LAN Name

If multiple Emulated LANs (ELANs) are present, you can enter a character string in
the Emulated LAN Name parameter. The LAN emulation client uses this parameter
to tell the LAN emulation services which ELAN it wants to join. By default, if a
SunATM LAN emulation client does not specify an ELAN name, it tells the services
to assign it to the default (or only) ELAN.

Note –

If you have multiple LAN emulation instances configured on a physical

interface, only one instance can join the default (unspecified) ELAN. You must
specify an ELAN name for all other instances.

Additional Hostnames

The SunATM software supports logical interfaces in the SunATM LAN emulation
environment. Logical interfaces allow you to assign multiple IP addresses to a single
LAN Emulation interface. A logical interface name consists of three parts: the device
name (in the case of SunATM LAN emulation,

lane

); the major number, which

corresponds to the

lane

instance number; and the minor number, which

distinguishes the logical interfaces on a single

lane

instance. The format of a LAN

Emulation logical interface name is

lane

N:X, where N is the major number and X is

the minor number (for example,

lane0:2

).
