IP Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your
EMG2926-Q10A will automatically calculate the subnet mask based on the IP address
that you assign. Unless you are implementing subnetting, use the subnet mask
computed by the EMG2926-Q10A.

DHCP Server
11.1
Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the EMG2926-Q10A’s LAN
as a DHCP server or disable it. When configured as a server, the EMG2926-Q10A provides the TCP/
IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on
your LAN, or else the computer must be manually configured.
11.1.1
What You Can Do
Use the
General
screen to enable the DHCP server (
Section 11.2 on page 93
).
Use the
Advanced
screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (
Section 11.3 on page 94
).
Use the
Client List
screen to view the current DHCP client information (
Section 11.4 on page
96
).
11.1.2
What You Need To Know
The following terms and concepts may help as you read through this chapter.
MAC Addresses
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02. Find out the MAC addresses of your network devices if you intend to add them
to the
DHCP Client List
screen.

DHCP Server Advanced Screen
This screen allows you to assign IP addresses on the LAN to specific individual computers based on
their MAC addresses. You can also use this screen to configure the DNS server information that the
EMG2926-Q10A sends to the DHCP clients.
To change your EMG2926-Q10A’s static DHCP settings, click

DESCRIPTION
DHCP Server
Select
Enable
to activate DHCP for LAN.
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (computers) to obtain TCP/IP configuration at startup from a server.
Enable the DHCP server unless your ISP instructs you to do otherwise. Select
Disable
to stop the EMG2926-Q10A acting as a DHCP server. When configured as a server, the
EMG2926-Q10A provides TCP/IP configuration for the clients. If not, DHCP service is
disabled and you must have another DHCP server on your LAN, or else the computers
must be manually configured. When set as a server, fill in the following four fields.
IP Pool Starting
Address
This field specifies the first of the contiguous addresses in the IP address pool for LAN.
Pool Size
This field specifies the size, or count of the IP address pool for LAN.

Server
The EMG2926-Q10A passes a DNS (Domain Name System) server IP address (in the
order you specify here) to the DHCP clients. The EMG2926-Q10A only passes this
information to the LAN DHCP clients when you enable
DHCP Server
. When you disable
DHCP Server
, DHCP service is disabled and you must have another DHCP sever on your
LAN, or else the computers must have their DNS server addresses manually configured.
