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

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

and vice versa.
y
Packets from Devices B and C will travel through

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.
y

Trunk Port 3
with tagged VID 3. Switch B will
recognize its VLAN, pass to port 5, and then remove tags received successfully by Device H.
Packets from Device H will travel through
Trunk Port 3
with PVID 3. Switch A will
recognize its VLAN and pass it to port 2, but will not remove tags received successfully by
Device D.
y
Packets from Device E will travel through
Trunk Port 3
with tagged VID 4. Switch B will
