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.
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
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” (

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.
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.
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,
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
).
