Additional notes
Important terms used with the 802.1Q tagging 
  • Port VLAN identifier (PVID) : A classification mechanism that associates a port with a specific VLAN. For example, a port with a PVID of 3 (PVID =3) assigns all untagged frames received on this port to VLAN 3.
  • Tagged frame : The 32-bit field (VLAN tag) in the frame header that identifies the frame as belonging to a specific VLAN. Untagged frames are marked (tagged) with this classification as they leave the switch through a port that is configured as a tagged port.
  • Untagged frame : A frame that does not carry any VLAN tagging information in the frame header.
By default, all switch ports are set as untagged members of VLAN 1 with all ports configured as PVID = 1.
