ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your NPort
5100A. The ARP command tells your computer to associate the NPort 5100A’s MAC address with the intended
IP address. You must then use Telnet to access the NPort 5100A, at which point the device server’s IP address
will be reconfigured.
ATTENTION
In order to use this setup method, both your
computer and the NPort 5100A must be connected to the same
LAN.
Or, you may use a cross-over Ethernet cable to connect the NPort 5100A directly to your computer’s
Ethernet card.
Your NPort 5100A must be configured with the factory default IP address—192.168.127.254
—
before executing the ARP command, as described below.
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort 5100A from your network administrator.
2. Obtain the NPort 5100A’s MAC address from the label on its bottom panel.
3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:
arp –s 192.168.200.100 00-90-E8-xx-xx-xx
This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx-xx is the MAC address for your
NPort 5100A (be sure to use the numbers determined in steps 1 and 2).
4. Next, execute a special Telnet command by typing:
telnet 192.168.200.100 6000
After issuing this command, a Connect failed message will appear, as shown here. After the NPort 5100A
reboots, its IP address should be updated to the new address, and you can reconnect using either Telnet,
Web, or Administrator to check that the update was successful.
