Description
Relay Mode
Indicates the DHCP relay mode operation. Possible modes are:
Enabled:Enable DHCP relay mode operation. When DHCP relay mode operation is
enabled, the agent forwards and transfers DHCP messages between the clients
and the server, if not located in the same subnet domain. The DHCP broadcast
messages will not be flooded for security considerations.
Disabled: Disable DHCP relay mode operation.
Relay Server
Indicates the DHCP relay server IP address.
Relay Information Mode Indicates the DHCP relay information mode option operation. Possible modes are:
Enabled: Enable DHCP relay information mode operation. When DHCP relay
information mode operation is enabled, the agent inserts specific information
(option 82) into a DHCP message when forwarding to the DHCP server and
removes it from a DHCP message when transferring it to the DHCP client. It only
works when DHCP relay operation mode is enabled.
Disabled: Disable DHCP relay information mode operation
