Indeed you cannot authenticate clients on your uplink port, just on a downlink port.
If you can create a mesh to another AP, you may be able to change the eth0 port to a downlink port and run a wired captive portal on it. But better/easier to get APs with multiple ethernet interfaces.

I am testing with a 303 model, which only has one port. It is possible that you simply cannot enable an authentication service on an uplink port, but I wanted to test the possibility. I hope someone can figure out how it can be done because it would help me quite a bit in my infrastructure.
Best regards, and thanks for your reply

what AP model are you using for this? generally you should not change E0 wired profile a sit is the uplink for the AP.
But you can create E1-E4 port profile and enable Cloud Guest
Here I am using AP505H that has 4x Ethernet ports and this is for E3.

Hi.
I know that is posible to have a wired profile for guest access on my access points, but I'm having problems trying to configure it from Aruba Central. I want to configure a Guest Cloud Portal working on a WLAN and Eth0. On WLAN i have no problem, but on Eth0 I get the IP address but I'm no having any authentication procedure. I have a specif local dhcp scope for this service. This is my configuration:
ip dhcp CP

Any idea why is not working?
Thank you in advanced
