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.

In conclusion, to use the hiD 6615 S223/S323 as Layer 2 switch, user should add the up- link port to all VLANs and create new VLAN including all ports. If the communication be- tween each VLAN is needed, FID should be same.

To configure FID, use the following command.
