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 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.
