The connected host sends the traffic on any VLAN, and it will reach the port, the switch will add the VLAN tag. The untagged VLANs are connected to the host or the servers. If VLAN 10 not allowed, then the frame will drop. If it is the tagged port, it will check the port if it allows the VLAN 10 to leave the tag intact and sends the frame. Switch 1 identifies the port 2 should forward the data to switch 2.When the frame enters into switch 1, it will add the VLAN tag ad pass to port 2.The host will send the frame without a tag.It is used for broadcast when it sends data from one host, and it will pass to all the hosts connected in the port. The sender will send a frame with a VLAN tag, and the receiver receives it. It uses the word ‘Trunk’ to refer to the tagged port. When the frames contain the VLAN tags, it is the tagged port. Let us look at the key differences between VLAN Tagged vs Untagged: Key Differences Between VLAN Tagged vs Untagged Head to Head Comparison Between Tagged vs Untagged (Infographics)īelow are the top 7 differences between VLAN Tagged vs Untagged: To connect these two VLANs, there are two cables required.
Assume that we have another set of the same configuration in another room.
Here all the PCs are connected in one switch and can be communicated with each other. Untagged VLANs: It is a port-based VLAN it has been divided single physical switch into multiple logical switches.īelow is the example for untagged VLAN: Switch A
