Parameters

ip-address: Specifies the IP address of a DHCP server. The DHCP relay agent forwards DHCP packets received from DHCP clients to this DHCP server.

Usage guidelines

The specified IP address of the DHCP server must not reside on the same subnet as the IP address of the DHCP relay agent interface. Otherwise, the DHCP clients might fail to obtain IP addresses.

You can specify a maximum of eight DHCP servers on an interface. The DHCP relay agent forwards the packets from the clients to all the specified DHCP servers.

If you do not specify an IP address, the undo dhcp relay server-address command removes all DHCP servers on the interface.

Examples

# Specify the DHCP server 1.1.1.1 on the relay agent interface VLAN-interface 10.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] dhcp relay server-address 1.1.1.1
