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.
After finished the above settings, click Apply to save the configuration. The settings will
take effect.
