Moxa EDS-G516E-4GSFP [53/116] Sample applications of vlans using moxa switches

Managed Ethernet Switch (UI_2.0_FW_5.x) Featured Functions

3-40

The Moxa switch supports three types of VLAN port settings:

• Access Port: The port connects to a single device that is not tagged. The user must define the default port

PVID that assigns which VLAN the device belongs to. Once the ingress packet of this Access Port egresses

to another Trunk Port (the port needs all packets to carry tag information), the Moxa switch will insert this

PVID into this packet so the next 802.1Q VLAN switch can recognize it.

• Trunk Port: The port connects to a LAN that consists of untagged devices, tagged devices, and/or switches

and hubs. In general, the traffic of the Trunk Port must have a Tag. Users can also assign a PVID to a Trunk

Port. The untagged packet on the Trunk Port will be assigned the default port PVID as its VID.

• Hybrid Port: The port is similar to a Trunk port, except users can explicitly assign tags to be removed from

egress packets.

The following section illustrates how to use these ports to set up different 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 configured 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 configured 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 configured 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 configured as an Access

Port with PVID 2.

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

Port with PVID 3.

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

with PVID 5.

• Port 7 connects a single untagged device and assigns it to VLAN 4; it should be configured as an Access

Port with PVID 4.

After the application is properly configured:

• 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.
