Parameters
None
Description
Use the dhcp select relay command to enable the relay agent on the current interface. Upon
receiving requests from an enabled interface, the relay agent will forward these requests to outside
DHCP servers for IP address allocation.
Use the undo dhcp select relay command to restore the default.
After DHCP is enabled, the DHCP server is enabled on an interface by default. That is, upon receiving
a client's request from the interface, the DHCP server allocates an IP address from the DHCP address
pool to the client.
When the working mode of the interface is changed from DHCP server to DHCP relay agent, neither
the IP address leases nor the authorized ARP entries will be deleted. However, these ARP entries may
conflict with new ARP entries generated on the DHCP relay agent; therefore, you are recommended to
delete the existing IP address leases when changing the interface working mode to DHCP relay agent.
Examples
# Enable the DHCP relay agent on VLAN-interface 1.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] dhcp select relay
