DHCP

What DHCP Does

A DHCP (Dynamic Host Configuration Protocol)

Server

allocates a valid IP address to a

DHCP

Client

(PC or device) upon request.

•

The client request is made when the client device starts up (boots).

•

The DHCP Server provides the

Gateway

and

DNS

addresses to the client, as well as

allocating an IP Address.

•

XRT-811 can act as a

DHCP server

.

•

Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP

client

.

This is the default Windows setting for the TCP/IP network protocol. However, Windows
uses the term

Obtain an IP Address automatically

instead of "DHCP Client".

•

You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your
LAN does not have other Routers, this means there must only be one (1) DHCP Server on
your LAN.)

Using XRT-811's DHCP Server

This is the default setting. The DHCP Server settings are on the

LAN

screen. On this screen,

you can:

•

Enable or Disable XRT-811's

DHCP Server

function.

•

Set the range of IP Addresses allocated to PCs by the DHCP Server function.

You can assign Fixed IP Addresses to some devices
while using DHCP, provided that the Fixed IP Addresses
are NOT within the range used by the DHCP Server.

Using another DHCP Server

You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP
Server, rather than XRT-811's, the following procedure is required.

1. Disable the DHCP Server feature in XRT-811. This setting is on the LAN screen.

2. Configure the DHCP Server to provide XRT-811's IP Address as the

Default Gateway

.

To Configure your PCs to use DHCP

This is the default setting for TCP/IP under Windows 95/98/ME.

See

Chapter 4 - Client Configuration

for the procedure to check these settings.
