What should you configure on the uplink port that connects to the rest of the switched infrastructure to carry traffic from all VLANs?

Carry traffic from multiple VLANs over one link by using VLAN tagging on a trunk. The uplink to the rest of the switched network should be configured as a trunk, and frames from different VLANs are tagged with their VLAN IDs according to the 802.1Q standard. This tagging lets the receiving switches distinguish which VLAN each frame belongs to, so many VLANs can share a single physical connection without mixing their traffic. 802.1Q defines how the tags are inserted (a small tag in the Ethernet frame) and how trunking works, including handling for a native VLAN where frames can be untagged. The other standards listed don’t enable carrying multiple VLANs on one uplink: one is a general Ethernet specification, another is Spanning Tree Protocol, and the last is a Wi‑Fi standard.
