Section IV - TCP/IP OR • 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 Address 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 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 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 installation of the OkiLAN 6010e. OKI OkiLAN 6010e User's Guide IV - 75 TCP/IP

running the BOOTP server.
Configuring the OkiLAN 6010e IP Ad-
dress with RARP
RARP is an acronym for

rotocol. 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.
