DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide
• – (Non-Member) – Specifies the port as not being a member of the VLAN, but the port can
become a member of the VLAN dynamically.
Next, determine which of the ports that are members of the new VLAN will be Tagged or Untagged
ports.
To set a port as either a Tagged or an Untagged port:
Highlight the first field of Tag/Untag 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.
Once you have toggled between Active and Inactive under State, press APPLY to make the additions or
deletions effective for the current session. To enter the changes into Non-volatile RAM, highlight Save
Changes from the main menu and press Enter.
In the following example screen, the VLAN “Accounting” – VID # 2 – has been added. Ports 1, 2, 14, 16,
and 17 are Egress ports (static members of “Accounting”).
Example of 802.1Q VLAN:
