TCP/IP
Assigning the OkiLAN 6120e IP
Address with BOOTP
BOOTP is an acronym for
BOOT
Strap
P
rotocol.
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.
