characters are the module ID(in standalone device it always equal 0, in stackable device it means switch ID), and
the last two characters are the port number. For example, "00030108" means the DHCP message receive form
VLAN ID 3, switch ID 1, port No 8. And the option 82 remote ID value is equal the switch MAC address.
Possible Relay Information 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 the agent receives a DHCP message that already contains relay agent information it
will enforce the policy. The 'Replace' policy is invalid when relay information mode is disabled. 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.
