42.1 DHCP Overview
This chapter shows you how to configure the DHCP feature.
DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual computers to
obtain TCP/IP configuration at start-up from a server. If you configure the OLT as a DHCP relay agent,
then the OLT forwards DHCP requests to DHCP server on your network. If you don’t configure the OLT as
a DHCP relay agent then you must have a DHCP server in the broadcast domain of the client
computers or else the client computers must be configured manually.
42.1.1 What You Can Do
• Use the
DHCP Status
screen (
) to display the relay mode.
• Use the
DHCP Relay
screen (
) to enable and configure global DHCPv4 relay.
• Use the
VLAN Setting
) to configure your DHCPv4 settings based on
the VLAN domain of the DHCPv4 clients.
• Use the
DHCP L2 Agent
screen (
) to configure the DHCP relay agent
information and Lightweight DHCPv6 Relay Agent (LDRA) settings.
• Use the
ONT Option
) to configure whether to have the OLT add
DHCP options for outgoing packets, and forward packets with DHCP options.
• Use the
Simulation
screen (
) to start or stop a DHCP client test to simulate
how an ONT gets IP address information from the DHCP server.
42.1.2 What You Need to Know
Read on for concepts on DHCP that can help you configure the screens in this chapter.
DHCP Modes
If there is already a DHCP server on your network, then you can configure the OLT as a DHCP relay
agent. When the OLT receives a request from a computer on your network, it contacts the DHCP server
for the necessary IP information, and then relays the assigned information back to the computer.
DHCPv4 Configuration Options
The DHCPv4 configuration on the OLT is divided into
Global
and
VLAN
screens. The screen you should
use for configuration depends on the DHCP services you want to offer the DHCP clients on your network.
Choose the configuration screen based on the following criteria:
