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 Wha t Yo u C a n Do
• Use the
DHC Pv4 Sta tus
screen (
Section 37.3 on page 324
) to display the relay mode.
• Use the
DHC Pv4 Re la y
screen (
Section 37.4 on page 324
) to enable and configure global DHCPv4
relay.
• Use the
VLAN Se tting
screen (
Section 37.4.6 on page 330
) to configure your DHCPv4 settings based on
the VLAN domain of the DHCPv4 clients.
• Use the
DHC Pv6 Re la y
screen (
Section 37.5 on page 333
) to enable and configure DHCPv6 relay.
37.1.2 Wha t Yo u Ne e d to Kno w
Read on for concepts on DHCP that can help you configure the screens in this chapter.
DHC P Mo de s
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.
DHC Pv4 C o nfig ura tio n O ptio ns
The DHCPv4 configuration on the Switch is divided into
G lo b a l
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:
•
G lo b a l
- 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.
