LAN Configuration

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.

In the dynamic address assignment mode, an IP address is 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.

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.

To discover which IP address was assigned to the router:

1Follow the steps in the previous section for ARP to bind the router MAC address to a temporary static IP address.

2Use the command arp –gto display your computer’s the IP-to-MAC address table.

This table contains two entries corresponding to the router MAC address. One of the entries contains the temporary static IP address you just bound to the router MAC address, and the other entry is the DHCP-assigned IP address. You can use the DHCP assigned address to access the router from any computer on the network.

Configuring the Additional LAN Settings

You can configure the following additional LAN settings:

System information including the system name, Telnet password, FTP settings, and the whether the Router Administration software or the Network Management System Console displays by default when you use the Ethernet port.
