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.

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.

To use ARP to resolve addresses in Windows:

1You 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.

Note: UNIX users see MAN Pages for ARP in your OS.

2After 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.

3If 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).

4Access the TCP/IP Configuration screen and enter the permanent IP address for the router.
