CHAPTER 35 DHCP This chapter shows you how to configure the DHCP feature. 35.1 DHCP Overview 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. 35.1.1 DHCP modes The 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. 35.1.2 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 as a DHCP server or to relay DHCP requests to different DHCP servers for clients in different VLAN. 35.2 DHCP Status Use this screen to look at the status of DHCP servers on the switch. To open this screen, click IP Application > DHCP. MS-7206 User's Guide 197
