Parameter 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 when they are not in the same subnet domain. And the
DHCP broadcast message won't be flooded for security considerations.
Disabled: Disable DHCP relay mode operation.
Relay Server:

between the clients and the server when they are not in the same subnet domain.
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 DHCP server and removes it
from a DHCP message when transferring to DHCP client. It only works when DHCP relay operation mode is enabled.
Disabled: Disable DHCP relay information mode operation.
Relay Information Policy:
Indicates the DHCP relay information option policy. When DHCP relay information mode operation is enabled, if agent
receives a DHCP message that already contains relay agent information it will enforce the policy. And it only works under
DHCP if relay information operation mode is enabled. Possible policies are:
Replace: Replace the original relay information when a DHCP message that already contains it is received.
Keep: Keep the original relay information when a DHCP message that already contains it is received.
Drop: Drop the package when a DHCP message that already contains relay information is received.
