Description

We use an HPE switch to implement MAC layer security. It is configured to snoop DHCP request & inject Option 82 (RFC 3046) to tell us exactly which port and chassis a client is connected to.

isc-dhcpd will record Option 82 in the lease file, but the pfSense GUI does not do anything with the information.

We understand there is a third-party patch for this, but it currently appears to be unmaintained, and may not have been updated for pfSense 2.3.1-x.

(This might well be a good fit for a more general package of Layer 2 security features in pfSense)

Our switch does not currently support the DHCPv6 Interface-ID option, (as in RFCs 3315, 4649, 4580) but we're keen to use these also.
