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. 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). Once connected through Telnet, the router’s IP address, subnet mask, and default gateway can be set up through menus described in Configuring the Router’s Network Settings on page 3-5.

Dynamic Host Configuration Protocol Configuration

The Dynamic Host Configuration Protocol (DHCP) is a protocol designed to make IP address assignment dynamic and automatic. When a router is configured in DHCP mode, it generates a request for an IP address. The address is provided to the router and can be used from that point forward. See Accessing the Router Administrator Using the Ethernet Port on page 3-3for accessing the Router Administrator software through the Ethernet port, including enabling DHCP.

In the dynamic address assignment mode, an IP address are leased to a DHCP-configured router. You should ask your system administrator to configure your network so the router can use DHCP, and host name you have assigned to the router. Accessing the Router Administrator Using the Ethernet Port on page 3-3presents configuring the router host name and the default host names for which the router has been configured.

In the event you configure your router to DHCP and do not know which IP address was assigned automatically, you can use ARP to discover which IP address was assigned to the router by the DHCP server.
