∙Your router(s) are configured to forward BOOTP packets between the OkiLAN 6010e’s subnet and the subnet of the host running the BOOTP server.

Configuring the OkiLAN 6010e IP Ad- dress with RARP

RARP is an acronym for Reverse Address Resolution Protocol. Every TCP/IP network device must have a unique 32-bit IP address. TCP/IP network devices will have both an IP address and a 48-bit Ethernet (network hardware) address. Ethernet addresses usually cannot be configured and are hard coded by the manufacturer of the device. RARP is a protocol used by devices that know their network hardware address, but do not know their IP address. When powering up on a network, a device that uses RARP will broadcast its network hardware address in a RARP request message. A RARP server (which may be a UNIX workstation) will re- spond with an IP address. The device will then know its IP address and use this address to perform subsequent TCP/IP transactions.

Note: Once the OkiLAN 6010e has been assigned an IP address, the OkiLAN 6010e configuration utility (which is accessed by telneting to the OkiLAN 6010e) or OkiNet for TCP/IP will allow you to change and/or make the IP address permanent. This means that a RARP server needs to be available only during installa- tion of the OkiLAN 6010e.
