Understanding the nomenclature of the Switch

IEEE 802.1Q Tagged and Untagged

Every port on an 802.1Q compliant switch can be configured as tagged or untagged.

Tagged

Ports with tagging enabled will put the VID number, priority and other VLAN

 

information into the header of all packets that flow into those ports. If a packet has

 

previously been tagged, the port will not alter the packet, thus keeping the VLAN

 

information intact. The VLAN information in the tag can then be used by other 802.1Q

 

compliant devices on the network to make packet-forwarding decisions.

 

 

 

 

Untagged

Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into

 

those ports. If the packet doesn't have an 802.1Q VLAN tag, the port will not alter the

 

packet. Thus, all packets received by and forwarded by an untagging port will have no

 

802.1Q VLAN information. (Remember that the PVID is only used internally within the

 

Switch). Untagging is used to send packets from an 802.1Q-compliant network device

 

to a non-compliant network device.
