V5808
276
To transmit the untagged packet from uplink port to subscriber, a new VLAN should
create including all subscriber ports and uplink ports. This makes the uplink ports to
recognize 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 V5808 as Layer 2 switch, user should add the uplink port to all
VLANs and create new VLAN including all ports. If the communication between each
VLAN is needed, FID should be same.
To configure FID, use the following command.
8.1.11 Sample Configuration
Sample Configuration 1: Configuring Port-based VLAN
The following is assigning br50, br3, and br4 to port 2, port 3, and port 4.
SWITCH(bridge)# vlan create br50
SWITCH(bridge)# vlan create br51
SWITCH(bridge)# vlan create br200
SWITCH(bridge)# vlan create br250
SWITCH(bridge)# vlan create br500
SWITCH(bridge)# vlan add br50 5/1,6/1 untagged
SWITCH(bridge)# vlan add br51 5/2,6/2 untagged
SWITCH(bridge)# vlan add br200 t/1-t/16 tagged
SWITCH(bridge)# vlan add br250 t/1-t/16 tagged
SWITCH(bridge)# vlan add br500 t/1-t/16 tagged
SWITCH(bridge)# vlan pvid 5/1,6/1 50
