All a bit trickier. The network access port it's just an indication of a switch to cut the tag of the Vlan packet. The receiver , such as a workstation, knows nothing about the mode of the switch port. Trunk indicates that the data are tagged with a Vlan. However, there are two exceptions to this Vlan 1, if you are talking about Cisco, the Cisco ideologii it is just the packages which do not have labels. And the second is specifying native vlan 200 for example, that will indicate that when traffic is moving label will be removed from the port. If we perform one of the two conditions, we will be able to trunk to simulate the behavior of the access port.
