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.
