Unlike DHCP relay, DHCP L2 Relay is used in the situation that the DHCP server and clients are in the same VLAN. In DHCP L2 Relay, in addition to normally assigning IP addresses to clients from the DHCP server, the switch can inform the DHCP server of some specified information, such as the location information, of clients by inserting an Option 82 payload to DHCP request When Option 82 is enabled on the AP, ePMP inserts “remote-id” (option ID 0×2) to be the SM’s MAC address and the “circuit-id” (ID 0×01) to be the AP’s MAC address. Those two fields are used to identify the remote device and connection from which the DHCP request was received. Option 82, or “Relay Information Option” is a field in DHCP messages used to identify the subscriber. The Option 82 field can already be filled in when a DHCP message is received at the router, or it can be empty. If the field is empty, the router should add identifying information (circuit ID, remote ID or both).
