3. Setup the P-660H-Tx v2 as a DHCP Relay

• What is DHCP Relay?

DHCP stands for Dynamic Host Configuration Protocol. In addition to the
DHCP server feature, the P-660H-Tx v2 supports the DHCP relay function.
When it is configured as DHCP server, it assigns the IP addresses to the LAN
clients. When it is configured as DHCP relay, it is responsible for forwarding
the requests and responses negotiating between the DHCP clients and the
server. See figure 1.

• Setup the P-660H-Tx v2 as a DHCP Relay

We could set the P-660H-Tx v2 as a DHCP Relay by the following command in
CLI:
Ip dhcp enif0 mode relay
Ip dhcp enif0 relay server [Server IP Address]
