Unmanaged Switch Vlan Tags

So what would happen if one put it in on a trunk.

Unmanaged switch vlan tags.

Can afford to get a 30 switch that can understand vlans. In this case the switch will flood the frame to all other ports configured with vlan 10. Neither will it have knowledge of what vlan is the native the only one on the trunk that is not tagged vlan. Well in my mind either the native vlan.

A lan can be divided into several vlans logically and only the hosts in a same vlan can communicate with each other. What an unmanaged switch that doesn t understand vlan tags will do with frames which have vlan tags a trunk link is really undefined. Vlan 1 is also the management vlan on switches that support management vlans. You must add the lag to the vlan as a single unit.

However if you have a mix of vlans on a switch it needs to be managed. The receiving switch will see the vlan tag and if the vlan is allowed it will forward the frame as required. Some switches will drop the frames as garbled some switches will pass them on as they are and some switches will strip the vlan tags. Running tags over a dumb switch just amounts to running multiple layer 3 on the layer 2 there is zero lack of.

If all of the things plugged into an unmanaged switch are on the same vlan then you can do that. What happens is when a trunk is confgured a header aka tag which varies in size depending on what encapsulation is used is added to the front of the a frame by doing this the destination knows which vlan it belongs when it arrives. For more information see what is a management vlan. If a port is a member of a link aggregation group lag or you plan to add it to a lag do not add it to a vlan or tag it individually.

Here are two configuration examples for 802 1q vlan. For example a broadcast may be received on vlan 10. Vlan virtual local area network is a technology that can solve broadcasting issues. The sender will send a frame with a vlan tag.

As the following figure shows the switch connects to two different groups.
