UNICOM Electric 8 - Manual (Page 54)

Support Protocol-based VLAN
In order for an end station to send packets to different VLANs, it must be
capable of either tagging packets it sends with VLAN tags or attach itself
to a VLAN-aware bridge. The bridge must be capable of classifying and
tagging the packets with a different VLAN ID based on not only default
PVID but also other information about the packet, such as the protocol.
5-4-7-1. Basic
Create a VLAN and add tagged member ports to it.
1. From the main menu, click administrator -- VLAN configuration.
2. Click Add
3. Type a name for the new VLAN.
4. Type a VID (between 2-4094). The default is 1.
5. From the Available ports box, select ports to add to the switch and click
Add.
6. Click Apply
5-4-7-2. Port VID
Configure port VID settings
From the main Tag-based (IEEE 802.1Q) VLAN page, click Port VID
Settings.
Port VID (PVID)
Sets the Port VLAN ID that will be assigned to untagged traffic on a given
port. For example, if port 9’s Default PVID is 100, all untagged packets on
port 9 will belong to VLAN 100. The default setting for all ports is VID 1.
This feature is useful for accommodating devices that you would like to
add to the VLAN but don’t support tagging. Only one untagged VLAN is
allowed per port.
