If the OkiLAN 6200e receives multiple responses, it will choose the first one.

When the OkiLAN 6200e receives an address, it sends an ARP message once every second for five seconds on the offered address to determine if another device is using it. If the OkiLAN 6200e finds another device is using the address, it will refuse the address and start looking for a new address.

Static Route Entry

When the OkiLAN 6200e is powered on or reset and no permanent IP address has been assigned, it will attempt to obtain an IP address through Gleaning, RARP, BOOTP or DHCP. If the OkiLAN 6200e has not determined its IP address after two minutes, the IP address will default to This IP address should only be used temporarily to configure a new, permanent IP address. To change to a permanent IP address, the route add command is used to place the OkiLAN 6200e product’s default IP address into the workstation’s network routing table. To use the route command, you must have Windows 95/98/ME, Windows NT/2000 or super-user privileges under UNIX. The syntax for this command is:

route add “IP address of the workstation” 0

Note: The zero (0) placed at the end of the route add command shown above is optional.

The Static Route method only works if the host from which you are telneting is on the same subnet as the OkiLAN 6200e. Once the route add command has been issued, telnet will allow you to change and/or make the IP address permanent. After changing the IP address to its permanent address, the routing table entry should be deleted using route delete.

For more information, consult your system documentation for the route command.


If an IP address has not been permanently assigned, the OkiLAN 6200e will use Reverse Address Resolution Protocol (RARP) or Bootstrap Protocol (BOOTP). The OkiLAN 6200e will broadcast requests for its IP address to both RARP and BOOTP servers. A RARP or BOOTP server will respond by searching a configuration file that maps the Ethernet hardware addresses of devices on the network to their respective IP addresses. If a match is found, the server’s response will include the IP address of the device.

Most UNIX operating systems support either the RARP or BOOTP protocol. To find out which protocol your operating system supports, request the manual page for the protocol’s daemon (e.g. man bootpd or man rarpd), or see your network manuals. Both protocols require that you add the product’s network hardware address and IP address to a configuration file. See your network documentation for instructions or refer to Application Considerations.

Note: An IP address received from a RARP or BOOTP server is not permanently programmed into the OkiLAN 6200e. Therefore, if you choose this method of assigning the IP address, the RARP or BOOTP server must be available every time the OkiLAN 6200e is powered on or reset. The IP address can be stored permanently using telnet, OkiNet for TCP/IP, OkiNet for NetWare or the OkiNet for VINES utility (may apply to
