Inbound tagged packets

The switch requires VLAN tagging on a given port if the port will be receiving inbound, tagged VLAN traffic that should be forwarded. Even if the port belongs to only one VLAN, it forwards inbound tagged traffic only if it is a tagged member of that VLAN.

If a tagged packet arrives on a port that is not a tagged member of the VLAN indicated by the packet's VID, the switch drops the packet.

Similarly, the switch drops an inbound, tagged packet if the receiving port is an untagged member of the VLAN indicated by the packet's VID.
