The following table describes the labels in this screen.
19.5 DHCP
DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual
computers to obtain TCP/IP configuration at start-up from a server. You can configure the
switch as a DHCP server or disable it. When configured as a server, the switch provides the
TCP/IP configuration for the clients. If you disable the DHCP service, you must have another
DHCP server on your LAN, or else the computer must be manually configured.
19.5.1 DHCP modes
Depending on your switch model, your switch can be configured as a DHCP server or DHCP
relay agent.
• If you configure the switch as a DHCP server, it will maintain the pool of addresses and
distribute them to your LAN computers.
• If there is an Ethernet device that performs the DHCP server function for your network,
then you can configure the switch as a DHCP relay agent. When the switch receives a
request from a computer on your network, it contacts the Ethernet device (the DHCP
server) for the necessary IP information, and then relays the assigned information back to
the computer.
19.5.2 Configuring DHCP Server
Follow the steps below to set the switch as a DHCP server.
1 In the Device Panel list, right-click on a device.
2 Click Configuration > IP Configuration > DHCP.
