Moxa Managed Ethernet Switch (UI_2.0_FW_5.x) User Manual
The f ollowing section illustrates how to use these ports to set up dif f erent applications.
Sample Applications of VLANs Using Moxa Switches
In this application:
• Port 1 connects a single untagged device and assigns it to VLAN 5; it should be conf igured as an
Access Port with PVID 5.
• 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 conf igured as a Hybrid 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 must belong to the same VLAN.
• Port 3 connects with another switch. It should be conf igured as a Trunk Port. GVRP protocol will be
used through the Trunk Port.
• Port 4 connects a single untagged device and assigns it to VLAN 2; it should be conf igured as an
Access Port with PVID 2.
• Port 5 connects a single untagged device and assigns it to VLAN 3; it should be conf igured as an
Access Port with PVID 3.
• Port 6 connect a single untagged device and assigns it to VLAN 5; it should be conf igured as an Access
Port with PVID 5.
• Port 7 connects a single untagged device and assigns it to VLAN 4; it should be conf igured as an
Access Port with PVID 4.
Af ter the application is properly conf igured:
• Packets f rom 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.
• Packets f rom Devices B and C will travel through Hybrid Port 2 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.
• Packets f rom Device D will travel through 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 successf ully by Device D.
• Packets f rom Device E will travel through Trunk Port 3 with tagged VID 4. Switch B will recognize its
VLAN, pass it to port 7, and then remove tags received successfully by Device I. Packets from Device I
will travel through Trunk Port 3 with tagged VID 4. Switch A will recognize its VLAN and pass it to port
2, but will not remove tags received successfully by Device E.
