ARP – Address Resolution Protocol
ARP (Address Resolution Protocol) is used to assign a temporary
IP address to a ethernet interface card so you can access it from
the Ethernet network. After establishing a temporary IP address,
you must manually store the IP address within the ethernet,
otherwise it will be lost once you power down the printer. Since
ARP does not update the IP address of the ethernet, the Ethernet
4400 utility will not show the IP address assigned by ARP. Instead,
it will show the IP address currently stored in the NIC.
IBM 4400 Ethernet Utility Troubleshooting
If the IBM 4400 Ethernet Utility cannot find the ethernet, check the
following:
•
Load the utility onto a Windows station on the same subnet as
the ethernet. The utility cannot see print servers across routers
unless BOOTP broadcast packets can travel from subnet to
subnet.
•
Wait several minutes for the utility to recognize the ethernet or
repower the printer.
•
Install the utility software on the same subnet. If you load the
utility on one subnet and your printer is on another, the utility
will not browse to the printer. Instead, it will browse to the
subnet that you loaded the utility on.
•
If you have a DHCP, RARP, or BOOTP server running that may
be providing the ethernet with an IP address upon bootup, the
utility is not needed to assign an IP address to the print server.
NOTE: If the ethernet has an IP address, it will no longer send out
a BOOTP packet. This means that the utility will not be able
to detect the device on the network.
