I know what access ports are, but I'm interested that the port can be on a single vlan, but not access, but tagged? Thanks in advance

Everything is a little trickier. From the network side, the access port is just an instruction to the switch to strip the Vlan tag from the packet. The receiver, such as a workstation, does not know anything about the switch's port mode. Trunk indicates that the data is tagged with Vlan. However, there are two exceptions - this is 1 Vlan, if we are talking about Cisco, in Cisco idiology, these are just packets that do not have a label. And the second is an indication of native-vlan 200, for example, which will indicate that when traffic passes, the label will be removed from the port. If we fulfill one of the two conditions, we can emulate the behavior of the access port on the trunk.
