OKI OkiLAN 6010e User’s Guide
Assigning the OkiLAN 6010e 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 ad-
dress. 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 run by accessing the OkiLAN 6010e 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 instal-
lation of the OkiLAN 6010e.
Address Formats
Network hardware addresses are 48-bits and are ex-
pressed in 6 bytes (hexadecimal format) usually sepa-
rated by colons. Each hexadecimal byte has a range
from 00 to FF.
Example: 00:40:68:17:50:A4
