4.3.3.3 VLAN Port Configuration
This page is used for configuring the Industrial Managed Switch port VLAN. The VLAN per Port Configuration page contains
fields for managing ports that are part of a VLAN. The port default VLAN ID (PVID) is configured on the VLAN Port Configuration
page. All untagged packets arriving to the device are tagged by the ports PVID.
Understand 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 t
hat 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.
