Hostname or IP Address
If IP traffic runs over a LAN Emulation instance, assign a hostname and
corresponding IP address to the instance. If you enter a hostname that appears in the
/etc/hosts
file, or if NIS, NIS+, or DNS is enabled and the hostname is resolvable
over it, you are not prompted to enter an IP address. Instead, the resolution is
performed automatically. If the hostname cannot be resolved, you are prompted to
enter an IP address. If you must enter an IP address, or if the address is only
available through NIS, NIS+, or DNS, the SunATM software updates the
/etc/
hosts
file.
A valid hostname is no more than 80 characters. A valid IP address is a set of four
decimal numbers in the range of 0 to 255, separated by dots (for example,
149.144.130.9
).
Local ATM Address
The local ATM address is the 20-byte ATM address associated with this LAN
Emulation instance. See “ATM Address Formats and Variables” on page 34 for more
information about ATM address formats and variables.
Each
lane
instance must be assigned a unique ATM address. Each SunATM adapter
has been assigned 16 unique MAC addresses; if you use the variable
$myaddress
for each
lane
instance, the SunATM software will automatically distribute those
MAC addresses to the
lane
instances associated with each physical interface.
LECS Indicator
Most LAN Emulation services include a LAN Emulation Configuration Server
(LECS), which is the first server contacted when bringing up a LAN Emulation
client. The LECS provides the ATM address of the LAN Emulation Server (LES), as
well as other configuration information about the emulated LAN. However, some
LAN Emulation services do not include an LECS, and the LES must be contacted
directly. With the LECS Indicator parameter, you specify which service should be
contacted first in your configuration. The possible values for this parameter are
displayed as individual options on the LAN Emulation Instance menu.
Note –
If the value of this parameter is
No LECS
, you must specify a value for the
LES ATM Address parameter.
