DHCP
37.1 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 Switch as a DHCP relay
agent, then the Switch forwards DHCP requests to DHCP server on your network. If you don’t
configure the Switch 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.
37.1.1 What You Can Do
• Use the
DHCPv4 Status
screen (
) to display the relay mode.
• Use the
DHCPv4 Relay
) to enable and configure global DHCP
relay.
• Use the
VLAN Setting
screen (
) to configure your DHCP settings based
on the VLAN domain of the DHCP clients.
• Use the
DHCPv6 Relay
screen (
) to enable and configure DHCPv6
relay.
37.1.2 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 Switch as a DHCP
relay agent. When the Switch 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.
DHCP Configuration Options
The DHCP configuration on the Switch 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:
•
Global
- The Switch forwards all DHCP requests to the same DHCP server.
•
VLAN
- The Switch is configured on a VLAN by VLAN basis. The Switch can be configured to relay
DHCP requests to different DHCP servers for clients in different VLAN.
