802.11q VLAN

My ProSAFE GS116E is configured for Advanced 802.1q VLAN mode. I’m wondering what happens when an Ethernet frame arriving to a port from the outside is tagged for a VLAN Group that the port is not a member of. I can think of three possibilities:

 

* The frame is dropped (ignored).

 

* The frame enters the switch with its current VLAN tag.

 

* The frame enters the switch but its tag is changed to the port’s default PVID.

 

Anyone know for sure?

 

Thanks.

  • Hello gfvalvo, 

     

    Answer number three is the correct one. It will let the frame enter the switch but it its tag will be changed to the port's VID.
