Section 4 - Appendix B - Application Considerations

Assigning the OkiLAN 6120e IP Address with BOOTP

BOOTP is an acronym for BOOTStrap Protocol. Every TCP/IP network device is required to have a unique 32-bit IP address assigned to it. TCP/IP network devices will have both an IP address and a 48 bit Ethernet/Token-Ring (network hardware) address. Ethernet addresses usually cannot be configured and are hard coded by the manufacturer of the device. BOOTP 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 BOOTP will broadcast its network hardware address in a BOOT request packet. A BOOTP server (which may be a UNIX workstation) will respond 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 6120e has been assigned an IP address, the OkiLAN 6120e configuration utility (which is run by accessing the OkiLAN 6120e using telnet) or OkiNet for TCP/IP will allow you to change and/or make the IP address permanent. This means that a BOOTP server needs to be available only during installation of the OkiLAN 6120e.

Address Formats

Network hardware addresses are 48-bits and are expressed in 6 bytes (hexadecimal format) usually separated by colons. Each hexadecimal byte has a range from 00 to FF.
