ARP ON WINDOWS
In order for the ARP command to work on Windows, the RP table on the PC must have at least one IP
address defined other than its own. If the ARP table is empty, the command will return an error message.
Type ARP –A at the DOS command prompt to verify that there is at least one entry in the ARP table.
If the local machine is the only entry, ping another IP address on your network to build a new entry in the
ARP table; the IP address must be a host other than the machine on which you are working. Once there
is at least one additional entry in the ARP table, use the following command to ARP the IP address to the
Ethernet Interface:
arp –s 191.12.3.77 00-20-4a-xx-xx-xx
TELNET TO PORT 1
Now open a Telnet connection to Port 1. The connection will fail quickly (3 seconds). But the Ethernet
Interface will temporarily change its IP address to the one designated in this step.
telnet 191.12.3.77 1
TELNET TO PORT 9999
Finally, open a Telnet connection to port 9999 and set all required parameters.
telnet 191.12.3.77 9999
NOTE: This IP address is temporary and will revert to the default value when the Ethernet Interface’s
power is reset, unless you log into the Ethernet Interface and store the changes permanently.
16.6: Network Configuration
Certain parameters must be configured before the Ethernet Interface can function on a network. The
Ethernet Interface can be locally or remotely configured using the following procedures:
Use a Telnet connection to configure the unit over the network. The Ethernet Interface’s configuration is
stored in nonvolatile memory (NVRam) and is retained without power. The configuration can be changed
at any time. The Ethernet Interface performs a reset after the configuration has been changed and
stored.
As mentioned above, to configure the Ethernet Interface over the network, establish a Telnet connection
to port 9999. From the Windows Start menu, click Run and type the following command, where x.x.x.x is
the IP address and 9999 is the Ethernet Interface’s fixed network configuration port number.
telnet x.x.x.x 9999
NOTE: Be sure to include a space between the IP address and 9999.
