/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)
