Which type of traffic is designed for a native VLAN?

The type of traffic that is designed for a native VLAN is the untagged traffic. A native VLAN is known to carry the untagged traffic. This traffic is a kind of traffic which its source is not from a VLAN. A data VLAN is generally recognized to carry user generated traffic.

In the case of a management traffic, this is being carried by a management VLAN. In few cases, a tagged port would receive an untagged frame. In order to be able to handle this, there is a special VLAN configured on tagged ports, which is referred to as the native VLAN.

Any untagged frame arriving on a tagged port is being attached to the native VLAN by the switch. If a frame that is the native VLAN gets to leave a tagged or trunk port, the VLAN tag would be stripped out by the switch. Thus, in carrying untagged traffic through one or more switches, you can use the native VLAN.

A native VLAN is also known as an untagged VLAN on the switch port. There are some newbies who become confused with the difference between a management VLAN and a native VLAN. The answer is that they are similar but they should be always differentiated for safety purposes.

Take note that if native VLAN would remain untagged, this can lead to some problems with your security. This explains why tagging the native VLAN is necessary. To answer the question, the required traffic for the native VLAN is the tagged VLAN for added security.
