In local mode, which switch port type does a lightweight AP use to connect to the wired network?

A lightweight AP in local mode primarily uses an access port to connect to the wired network. This is because the AP itself is typically treated as an end device, similar to a computer or printer, and it needs to be on a specific VLAN to communicate with the Wireless LAN Controller (WLC) and pass client traffic. An access port assigns the port to a single VLAN. EtherChannel and LAG (Link Aggregation Group) are terms for bundling multiple physical links into a single logical link for increased bandwidth and redundancy; they describe a link aggregation method, not a port type for a single AP connection. A trunk port is used to carry traffic for multiple VLANs, typically between switches or between a switch and a WLC, but not usually for a single AP in local mode.
