B. DHCP Server :
Dynamic Host Configuration Protocol (DHCP) is a communications protocol that allows network
administrators to manage and assign IP addresses to computers within the network. DHCP
provides a unique address to a computer in the network which enables it to connect to the Internet
through Internet Protocol (IP). DHCP is controlled by the DHCP Server. The following settings
allow you to configure the DHCP server.
DHCP Server: Select Enabled (default) to activate DHCP Server.
DHCP Address Pool Selection: Two types of Address Pool selections are available, with
System Allocated as the default.
System Allocated: The DHCP address pool is based on LAN port IP address plus
12 IP addresses. For example, when the LAN IP address is 10.0.0.2; the DHCP
address pool the range from 10.0.0.3 to 10.0.0.14.
User Defined: When User Defined is selected, the DHCP address pool starts at the
User Defined Start Address and ends at the User Defined End Address. The
maximum pool size can be 253 IP addresses: 255 total IP addresses – 1 broadcast
address – 1 LAN port IP address.
User Defined Start Address: This is the starting IP address of the DHCP pool for User
Defined DHCP Address Pool Selection.
Note : Range for User Defined Start Address is x.x.x.x, where 0
value is 10.0.0.4.
User Defined End Address: This is the last IP address in the DHCP pool. User Defined
DHCP Address Pool Selection.
Note : Range for User Defined End Address is x.x.x.x, where 0
value is 10.0.0.15.
DHCP Gateway Selection: The default setting for the DHCP Gateway Selection is Automatic.
You can select User Defined and specify User Defined Gateway Address. The DHCP server
will issue the User Defined Gateway Address to the LAN DHCP clients.
User Defined Gateway Address: The purpose for the User Defined Gateway Address is to
have two gateway addresses, as the LAN IP Address at the top of the LAN Configuration
page is also a gateway address.
Lease time: The Lease time is the amount of time a network user will be allowed to connect
with DHCP server. If all fields are 0, the allocated IP addresses will be effective forever.
Note : Ranges for Lease Time fields: Days 0-36500, Hours 0-23, Minutes 0-59, Seconds 0-59,
default value is 1 days 0 hours 0 minutes 0 seconds.
User mode: Under the Single User mode, the DHCP server only allocates one IP address to a
local PC. Under the Multiple User mode (default), the DHCP server allocates the IP
addresses specified by the DHCP address pool.
