Access Port

Access ports are usually configured at ports which connect to end devices like hosts or servers. Access ports are members of one VLAN. Hence, the frames sent or received by an end device are without any tag.


Trunk Port

The Trunk port interface will always be a trunk. Irrespective of occurrences on the other side. DTP is also used to negotiate a neighbouring interface that is set to dynamic auto in a trunk.

The dynamic desirable port will attempt to actively convert the links to a trunk link. The port becomes a trunk if the other end switch port is set to trunk.
