and/or switches and hubs. In general, the traffic of the Trunk Port must have a Tag. Users can
also assign PVID to a Trunk Port. The untagged packet on the Trunk Port will be assigned the
port default PVID as its VID.
The following section illustrates how to use these ports to set up different applications.

In this application,
y Port 1 connects a single untagged device and assigns it to VLAN 5; it should be configured as
Access Port with PVID 5.
y Port 2 connects a LAN with two untagged devices belonging to VLAN 2. One tagged device
with VID 3 and one tagged device with VID 4. It should be configured as Trunk Port with
PVID 2 for untagged device and Fixed VLAN (Tagged) with 3 and 4 for tagged device. Since
each port can only have one unique PVID, all untagged devices on the same port can only
belong to the same VLAN.
y Port 3 connects with another switch. It should be configured as Trunk Port GVRP protocol
will be used through the Trunk Port.
y Port 4 connects a single untagged device and assigns it to VLAN 2; it should be configured as
Access Port with PVID 2.
y Port 5 connects a single untagged device and assigns it to VLAN 3; it should be configured as
Access Port with PVID 3.
y Port 6 connect a single untagged device and assigns it to VLAN 5; it should be configured as
Access Port with PVID 5.
y Port 7 connects a single untagged device and assigns it to VLAN 4; it should be configured as
Access Port with PVID 4.
After proper configuration:
y Packets from Device A will travel through Trunk Port 3 with tagged VID 5. Switch B will
recognize its VLAN, pass it to port 6, and then remove tags received successfully by Device G,
and vice versa.
y Packets from Devices B and C will travel through Trunk Port 3 with tagged VID 2. Switch B
recognizes its VLAN, passes it to port 4, and then removes tags received successfully by
Device F, and vice versa.
