Highlight the first field of Tagging (U/T):[ ][ ][ ] field. Each
port’s state can be set by highlighting the port’s entry using the
arrow keys and then toggling between U or T using the space bar.
U - specifies the port as an Untagged member of the VLAN.
When an untagged packet is transmitted by the port, the
packet header remains unchanged. When a tagged packet
exits the port, the tag is stripped and the packet is changed
to an untagged packet.
T - specifies the port as a Tagged member of the VLAN.
When an untagged packet is transmitted by the port, the
packet header is changed to include the 32-bit tag
associated with the PVID (Port VLAN Identifier – see
below). When a tagged packet exits the port, the packet
header is unchanged.
If the port is attached to a device that is not IEEE 802.1Q VLAN
compliant (VLAN-tag unaware), then the port should be set to U –
Untagged.
If the port is attached to a device that is IEEE 802.1Q VLAN
compliant, (VLAN-tag aware), then the port should be set to T –
Tagged.
