ip dhcp relay server

This command specifies the addresses of DHCP servers to be used by the switch’s DHCP relay agent. Use the no form to clear all addresses.

Syntax

ip dhcp relay server address1 [address2 [address3 ...]] no ip dhcp relay server

address - IP address of DHCP server. (Range: 1-3 addresses)

Default Setting

None

Command Mode

Interface Configuration (VLAN)

Usage Guidelines

You must specify the IP address for at least one DHCP server. Otherwise, the switch’s DHCP relay agent will not forward client requests to a DHCP server.

To start DHCP relay service, enter the ip dhcp restart relay command.

Example

Console(config)#interface vlan 1

Console(config-if)#ip dhcp relay server 10.1.0.99

Console(config-if)#
