A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical layout. Hosts in the same VLAN communicate with each other as if they are in a LAN. However, hosts in different VLANs cannot communicate with each other directly.  

Now let´s learn how to configure the tag VLAN on Web Smart Switch by the following example:

Network Topology:

Here we take TL-SG2216WEB which has 16 ports as an example.

Switch A connects to Switch B with an Ethernet cable in port 1.Switch A connects to the Internet via TL-R480T in port 16. 

The computers of Finance Dept. connect to port2-8 of switch A and port2-8 of switch B. The Sales Dept. connect to port 9-14 of switch A and port 9-14 of switch B.

Purpose:

1 The computers from Finance Dept. can communicate with each other.

2 The computers from Sales Dept. can communicate with each other.

3 The computers of Finance Dept. and Sales Dept. can´t communicate with each other.

4 Both the Finance Dept. and Sales Dept. can go to Internet through TL-R480T.

VLAN Configuration parameters:

To achieve the purpose, we configure 3 VLANs:VLAN2,VLAN3,VLAN4.

To achieve Purpose 1, we create the VLAN2 (VID=2):

Switch A:

Port:port1-8,16.

The egress frame of Port 1 is Add Tag, The rest are Drop Tag.

VIDs are 2 as default. PVIDs of Port 2-8 are 2

Switch B:

Port :port1-8  

The egress frame of Port 1 is Add Tag, The rest are Drop Tag.

VIDs are 2 as default. PVIDs for Port 2-8 are 2

To achieve Purpose 2, we create the VLAN3(VID=3):

Switch A:

Port:port1,9-14,16

The egress frame of Port 1 is Add Tag, The rest are Drop Tag.

VIDs are 3 as default. PVIDs of Port 9-14 are 3.

Switch B:

Port :port1,9-14.  

The egress frame of Port 1 is Add Tag, The rest are Drop Tag.

VIDs are 3 as default. PVIDs of Port 9-14 are 3.

In fact, we have already achieved the Purpose 3 by setting VLAN2 and VLAN3.

To achieve Purpose 4, we create the VLAN4(VID=4).PVID of Port 16 is 4.

Switch A:

Port:port1-14,16.

The egress frame of Port 1 is Add Tag, The rest are Drop Tag. VIDs are 4 as default.

Switch B:

Port :port1-14.  

The egress frame of Port 1 is Add Tag, The rest are Drop Tag. VIDs are 4 as default.

Now ,let’s start to configure Switch A:

Part I:Defining VLAN Mode:

Please go to VLAN Setting->VLAN Mode to choose the Tag VLAN(802.1Q Tag VLAN).

Part II: Setting VLANs:

Please go to VLAN Setting->Tag VLAN Setting to set the parameters of VLAN.

The Tag VLAN Setting page contains a table that maps VLAN parameters to ports. A port becomes a member of a certain VLAN when it is ticked.

Step 1:Choose the VLAN 2.

 

Step 2:Tick the port which is assigned to VLAN 2.Then click submit.

 

Step 3:Set the parameters for VLAN 3 and VLAN 4.Don’t forget to submit.

Part III: Tag VLAN Global Setting

Please go to VLAN Setting->tag VLAN Global Setting to set the PVID parameters.

PVID assigns a VLAN ID to untagged packets. Please set the PVID for ports in the Tag VLAN Global Setting page.

Until now, we have finished the configuration for Switch A.

Configure Switch B

Please configure Switch B in the same way. Here is a screen shot of Tag VLAN Global Setting of Switch B.

 

Now, the network will work as described in Purpose.
