dhcp select

Use dhcp select to enable the DHCP server or DHCP relay agent on an interface.

Use undo dhcp select to disable the DHCP server or DHCP relay agent on an interface. The interface discards DHCP packets.

Syntax

dhcp select { relay | server }

undo dhcp select { relay | server }

Default

The interface operates in DHCP server mode and responds to DHCP requests with configuration parameters.

Predefined user roles

Parameters

relay: Enables the DHCP relay agent on the interface.

server: Enables the DHCP server on the interface.

Usage guidelines

Before changing the DHCP server mode to the DHCP relay agent mode on an interface, use the reset dhcp server ip-in-use command to remove address bindings and authorized ARP entries. These bindings might conflict with ARP entries that are created after the DHCP relay agent is enabled.

Examples

# Enable the DHCP relay agent on VLAN-interface 2.

<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] dhcp select relay
