Access ports typically connect to end systems such as PCs and printers, while trunk ports typically connect to other switches and are used to carry multiple
VLANs.
There are two main port modes for a Layer 2 interface: access mode and trunk mode.
Access Mode: In Access Mode, the interface is configured to connect to a single end device, such as a host or server. The interface sends and receives Ethernet frames that are untagged, meaning they do not contain any VLAN identification information. By default, an access port is assigned to a single VLAN, known as the access VLAN. When a frame arrives on an access port, it is forwarded to the access VLAN and any other ports assigned to that VLAN.
Trunk Mode: In Trunk Mode, the interface is configured to carry traffic for multiple VLANs over a single physical link. The interface sends and receives Ethernet frames that are tagged with VLAN identification information. This tagging allows the receiving switch to identify which VLAN each frame belongs to, and to forward it to the appropriate ports. A trunk port can carry traffic for many VLANs, including the native VLAN, which is the VLAN that is not tagged.
Dual Mode and Tag Mod are not valid port modes for a Layer 2 interface.
