Unmanaged Switch Vlan Tags

In this case the switch will flood the frame to all other ports configured with vlan 10.

Unmanaged switch vlan tags. Here are two configuration examples for 802 1q vlan. What an unmanaged switch that doesn t understand vlan tags will do with frames which have vlan tags a trunk link is really undefined. You have two options either connect the ap directly to the 3560 or buy a managed switch as said. Well in my mind either the native vlan.

You must add the lag to the vlan as a single unit. For example a broadcast may be received on vlan 10. 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. Here you can see this process in action.

A lan can be divided into several vlans logically and only the hosts in a same vlan can communicate with each other. The receiving switch will see the vlan tag and if the vlan is allowed it will forward the frame as required. The sender will send a frame with a vlan tag. Can afford to get a 30 switch that can understand vlans.

However if you have a mix of vlans on a switch it needs to be managed. Neither will it have knowledge of what vlan is the native the only one on the trunk that is not tagged vlan. So what would happen if one put it in on a trunk. Vlan 1 is also the management vlan on switches that support management vlans.

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. Vlan virtual local area network is a technology that can solve broadcasting issues. For more information see what is a management vlan. Simply put the unmanaged switch would not be able to know what vlans it would or would not send over the link that might or might not be a trunk.

Running tags over a dumb switch just amounts to running multiple layer 3 on the layer 2 there is zero lack of.
