Overview

Dynamic Host Configuration Protocol (DHCP), an extension of the Bootstrap Protocol (BootP), is used to dynamically provide host configuration information to the workstations. To lower administrative overhead, network managers prefer to configure a small number of DHCP servers in a central location. Using few DHCP servers requires the routers connecting to the subnets or bridge (or VLANs) domains to support the BootP/DHCP relay function so that hosts can get the configuration information from servers several router hops away.

For information about configuring DHCP on a VLAN, see Configuring Switching Operations for the Passport 8000 Series Switch Using Device Manager Release 5.1.x.

Note: BootP/DHCP relays are supported on only IP routed port-based VLANs and protocol-based VLANs. BootP/DHCP relays are not supported on IP subnet-based VLANs.
