Description
Indicates whether to enable the DHCP L2
Relay.
The DHCP relay is a process in which cross-
subnet forwarding of DHCP broadcast
packets is implemented between the DHCP
client and the DHCP server. In this manner,
the DHCP clients in different physical
subnets can obtain IP addresses which are
dynamically allocated from the same DHCP
server.
l If Mode of the WAN port is Route, the IP
address of the ONT is obtained from
upper-layer DHCP servers in different
subnets and the user-side IP addresses are
obtained from the DHCP address pool of
the ONT.
l If Mode of the WAN port is Bridge, the
ONT functions as a bridge. Thus, the ONT
does not have an IP address. The user-side
IP addresses are obtained from upper-
layer DHCP servers in different subnets.
Indicates the start IP address in the IP address
pool on the primary DHCP server. It must be
in the same subnet as that of the IP address set
in "LAN Host Configuration". Otherwise,
the DHCP server fails to work normally.
Indicates the end IP address in the IP address
pool on the active DHCP server. It must be in
the same subnet as that of the IP address set
in "LAN Host Configuration". Otherwise,
the DHCP server fails to work.
Indicates the lease time of the IP address pool
on the active DHCP server. Options: minute,
hour, day, and week.
Indicates whether to enable the secondary
DHCP server. If the check box is selected,
you can set the secondary DHCP server.

DHCP server.
