Configuring DHCP L3
Relay Service
If the switch is configured to provide L3 DHCP Relay service use the IP Service >
DHCP > Relay page to configure L3 DHCP relay service for attached host devices. To
configure L2 or L3 DHCP relay service refer to the CLI Reference Guide DHCP Relay
settings of the CLI Reference Guide - specifically the command: ip dhcp l2/l3 relay.
If L3 DHCP relay is enabled, and this switch sees a DHCP request broadcast, it inserts
its own IP address into the request so that the DHCP server will know the subnet
where the client is located. Then, the switch forwards the packet to the DHCP
server. When the server receives the DHCP request, it allocates a free IP address for
the DHCP client from its defined scope for the DHCP client’s subnet, and sends a
