Sample Applications of VLANs using the EDS-828

In this application,

• Port 1 connects a single untagged device and assigns it to VLAN 5; it should be configured as “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 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.

• Port 3 connects with another switch. It should be configured as “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 configured as “Access Port”

with PVID 2.

• Port 5 connects a single untagged device and assigns it to VLAN 3; it should be configured as “Access Port”

with PVID 3.

• Port 6 connect a single untagged device and assigns it to VLAN 5; it should be configured as “Access Port”

with PVID 5.

• 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:

• 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.

• Packets from device 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.

• Packets from 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 successfully by device D.

• Packets from 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.
