To transmit the untagged packet from uplink port to subscriber, a new VLAN should be
created including all subscriber ports and uplink ports. This makes the uplink ports to rec-
ognize all other ports.
FID helps this packet forwarding. FDB is MAC Address Table that recorded in CPU. FDB
table is made of FID (FDB Identification). Because the same FID is managed in the same
MAC table, it can recognize how to process packet forwarding. If the FID is not same, the
system cannot know the information from MAC table and floods the packets.

To configure FID, use the following command.
