Using Address Resolution Protocol
The ARP configuration method requires no IP address re-configuration of any computer
on the network. The ARP command is available in various forms and sometimes with
varying syntax in UNIX and Windows systems.
All routers are shipped with a unique Media Access Control (MAC) hardware address
(sometimes referred to as a physical address). Chaparral Network Storage MAC addresses
have the format “00-50-13-fx-xx-xx,” where “x-xx-xx” is unique to each router. The
router MAC address can be found on a label on the bottom of the router.
To use ARP to resolve addresses in Windows:
1
You must first place the MAC address of the router being set up into your computer’s
ARP cache using the following command:
arp -s [IP address] 00:50:13:fx-xx-xx.
In this command, 00-50-13-fx-xx-xx is the router’s unique MAC address and IP
address is the IP address you or your LAN system administrator have chosen to use
as the IP address for the router.
This ARP command adds a static MAC-to-IP address binding to your computer. For
example, if you wanted to bind the router with the factory MAC address of 00-50-13-
f0-10-00 to the IP address 169.205.7.22, you should type arp –s 169.205.7.22 00-50-
13-f0-10-00.
2
After entering the MAC address-to-IP address mapping into your computer’s ARP
cache, you can issue the command ping 169.205.7.22 to send a request to the router.
If the router addressed by the ping command does not respond, check the LAN
connection on the router.
3
If the ping command addressed to the router was successful, use Telnet to access the
router using the IP address you just configured (for example, 169.205.7.22).
4
Access the TCP/IP Configuration screen and enter the permanent IP address for the
router.
See
Configuring the Additional LAN Settings on page B-3
.
Note: TCP/IP protocol requires that all devices in a subnet have the same
octets, typically for the first three octets. For example, to use the default
Chaparral IP address of 10.0.0.1, other computers on the subnet must be
10.0.0.X, where X is the value between 2 and 254. ARP is useful because
you can temporarily assign a compatible IP address to the router.
Note: UNIX users see MAN Pages for ARP in your OS.
