Unmanaged Switch Vlan Tags

Neither will it have knowledge of what vlan is the native the only one on the trunk that is not tagged vlan.

Unmanaged switch vlan tags.

A lan can be divided into several vlans logically and only the hosts in a same vlan can communicate with each other. 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. 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 you can see this process in action. So what would happen if one put it in on a trunk. For example a broadcast may be received on vlan 10. Here are two configuration examples for 802 1q vlan.

As the following figure shows the switch connects to two different groups. The receiving switch will see the vlan tag and if the vlan is allowed it will forward the frame as required. Well in my mind either the native vlan. For more information see what is a management vlan.

You must add the lag to the vlan as a single unit. In this case the switch will flood the frame to all other ports configured with vlan 10. Can afford to get a 30 switch that can understand vlans. What an unmanaged switch that doesn t understand vlan tags will do with frames which have vlan tags a trunk link is really undefined.

However if you have a mix of vlans on a switch it needs to be managed. Vlan 1 is also the management vlan on switches that support management vlans. 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.

If all of the things plugged into an unmanaged switch are on the same vlan then you can do that.
