To use the Service Port on a Wireless LAN Controller (WLC), the following are typically required:
- The service port interface must be connected to a switch.
- You must add static routes to the WLC.
- The switchport must be configured to be a trunk. (This one is typically necessary if you want to allow multiple VLANs over the connection).
So the correct choices are:
- The service port interface must be connected to a switch.
- You must add static routes to the WLC.
- The switchport must be configured to be a trunk.
However, please note that specifics might vary based on the exact configuration and deployment scenario, so it's always good to refer to the official documentation for your particular WLC model.
