14.3.2 Commands for DHCP Relay Configuration

14.3.2.1 ip forward-protocol udp
Command: ip forward-protocol udp <port>
no ip forward-protocol udp <port>
Function: Sets DHCP relay to forward UPD broadcast packets on the port; the "no ip
forward-protocol udp <port>" command cancels the service.
Default: None.
Command mode: Global Mode
Usage Guide: The forwarding destination address is set in the "ip helper-address"
command and described later.
Example: Setting DHCP packets to be forwarded to 192.168.1.5.
Switch(config)#ip forward-protocol udp boots
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip helper-address 192.168.1.5
14.3.2.2 ip helper-address
Command: ip helper-address <ip-address>
no ip helper-address <ip-address>
Function: Specifies the destination address for the DHCP relay to forward UDP packets.
The "no ip helper-address <ip-address>" command cancels the setting.
Default: None.
Command mode: Port mode
Usage Guide: The DHCP relay forwarding server address corresponds to the port
forwarding UDP, i.e. DHCP relay forwards corresponding UDP packets only to the
corresponding server instead of all UDP packets to all servers. When this command is
run after "ip forward-protocol udp <port>" command, the forwarding address
configured by this command receives the UDP packets from <port>. The combination of
"ip forward-protocol udp <port>" command and this command should be used for
configuration.

Scenario 1:
Too save configuration efforts of network administrators and users, a company is
using ES4624-SFP/ES4626-SFP switch as a DHCP server. The Admin VLAN IP address
