Configuring a Tag-based (IEEE 802.1Q) VLAN

Tag-based VLANs are based on IEEE 802.1Q specifications. Traffic is forwarded to VLAN member ports based on identifying VLAN tags in data packets. You can also configure the switch to interoperate with existing tag-based VLAN networks and legacy non-tag networks.

To configure a tag-based VLAN

1. Create a VLAN and add tagged member ports to it.
   
   
   • From the main menu, click VLAN Configuration, then click 802.1Q VLAN Operation Mode.
   • Click Add.
     
   • Type a name for the new VLAN.
   • Type a VID (between 2-4094). The default is 1.
   • Select protocol VLAN. The default is NONE.
   • From the Available ports box, select ports to add to the switch and click Add.
     
   • Click Next.
     
     

   By adding ports to the VLAN you are also tagging of traffic on that port. This means that traffic leaving the switch has a unique identifier (VLAN ID) that is used to specify traffic from different VLANs.

2. VLAN filter .
   
   
   • Port VID (PVID)
     Port VLAN ID that will be assigned to untagged traffic on a given port. For example, if port 10's Default PVID is 100, all untagged packets on port 10 will belong to VLAN 100. The default setting for all ports is VID 1.

     This feature is useful for accomodating devices that you want to participate in the VLAN but that don't support tagging. Only one untagged VLAN is allowed per port.
     

   • Ingress Filtering
     Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the port belongs to that VLAN. Disabling this setting will cause all frames to be forwarded, regardless of the port's VLAN setting.
