/ATMADDRESS=LES sets the LAN emulation server (LES) address for asynchronous transfer mode (ATM). Usually the address is not user specified, and this qualifier is used only if you want a specific address. By default the address is determined by software from the configuration server for the LES. The /ATMADDRESS=LES qualifier's syntax is as follows: SET DEVICE/ATMADDRESS = ([NO]LES=the ATM server) /ATMADDRESS=ARP sets the address resolution protocol (ARP) server address for Classical IP over ATM. This qualifier is required before a LIS is enabled if the local host is not the ARP server. The /ATMADDRESS=ARP qualifier's syntax is as follows: SET DEVICE/ATMADDRESS = (ARP=atm_arp_server)
