5-4-7-2. Port VID 
To configure port VID settings:  
From the main 802.1Q VLAN page, click Port VLAN ID Settings. 
 
 
 
VLAN ID   
Set the port VLAN ID that will be assigned to untagged traffic on a given 
port. This feature is useful for accommodating devices that you want to 
participate in the VLAN but that don’t support tagging.  Only one untagged 
VLAN is allowed per port.  Other VLANs need to be tagged. The VLAN ID 
must be the same as the VLAN ID of the port that belongs to the VLAN 
group, or the untagged traffic will be dropped. 
 
Ingress Filtering  
Ingress filtering lets frames belonging to a specific VLAN to be forwarded if 
the port belongs to that VLAN.
