Unmanaged Switch Vlan Tags

The receiving switch will see the vlan tag and if the vlan is allowed it will forward the frame as required.

Unmanaged switch vlan tags.

What an unmanaged switch that doesn t understand vlan tags will do with frames which have vlan tags a trunk link is really undefined. A lan can be divided into several vlans logically and only the hosts in a same vlan can communicate with each other. As the following figure shows the switch connects to two different groups. Vlan 1 is also the management vlan on switches that support management vlans.

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. Vlan virtual local area network is a technology that can solve broadcasting issues. Can afford to get a 30 switch that can understand vlans. For example a broadcast may be received on vlan 10.

You must add the lag to the vlan as a single unit. 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. Neither will it have knowledge of what vlan is the native the only one on the trunk that is not tagged vlan. The sender will send a frame with a vlan tag.

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. 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. Here are two configuration examples for 802 1q vlan. For more information see what is a management vlan.

You have two options either connect the ap directly to the 3560 or buy a managed switch as said. Running tags over a dumb switch just amounts to running multiple layer 3 on the layer 2 there is zero lack of. Well in my mind either the native vlan. If all of the things plugged into an unmanaged switch are on the same vlan then you can do that.

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