Which port type does a lightweight AP use to connect to the wired network when configured in FlexConnect mode with local switching and VLAN tagging?

When an AP operates in FlexConnect mode with local switching and VLAN tagging, it acts as a mini-switch, requiring the ability to send and receive traffic for multiple VLANs (e.g., data, voice, management) while preserving their VLAN tags. A trunk port on the connected switch is specifically designed to carry traffic for multiple VLANs by tagging each frame with its corresponding VLAN ID, thus fulfilling this requirement.

LAG (Link Aggregation Group) bundles multiple physical links for increased bandwidth and redundancy, but it does not define the port's VLAN-handling capabilities (i.e., whether it's an access or trunk port).

EtherChannel is Cisco's proprietary implementation of LAG, and like LAG, it aggregates links for bandwidth and redundancy rather than defining the specific VLAN tagging behavior of the port itself.

An access port is configured to carry traffic for only a single VLAN and typically removes VLAN tags, which would prevent the AP from properly handling and forwarding traffic for multiple tagged VLANs.
