Configuring a LAN Emulation Interface
LAN Emulation, standardized by the ATM Forum’s LAN Emulation 1.0 specification, is another way of providing TCP/IP and UDP/IP support over an ATM interface. Address resolution information is provided by a series of LAN Emulation services. When a LAN Emulation interface is brought up, it must “join the LAN;” that is, it must register with these services. This process, and the address resolution process are described in “LAN Emulation” on page 69.
Unlike Classical IP, the LAN Emulation protocol provides a broadcast service to the upper layer protocols. Therefore, the multicast and broadcast limitations described in “Configuring a Classical Internet Protocol Interface” on page 44 do not affect LAN emulation interfaces.
Editing the laneconfig File
The /etc/opt/SUNWconn/atm/laneconfig file contains the required configuration information for each interface that uses LAN Emulation. One entry is required for each SunATM interface.
Each time you modify the /etc/opt/SUNWconn/atm/laneconfig file, run the LAN Emulation setup program (lanesetup). lanesetup is in the /etc/opt/SUNWconn/atm/bin directory.
Each /etc/opt/SUNWconn/atm/laneconfig entry follows this format:
Interface | MAC Address/ | ATM Address VCI Flag |
| ELAN Name |
|
