Error code meaning and how to solve it

[agent_halal]

Hello, I am trying to setup my Ruckus ICX 7150 C12P running router code. I am trying to follow this video (around the 51:00 mark + or - a few mins) https://www.youtube.com/live/TNVuHk8e-zM?si=9DsiNzXt3szFlM1S . When I type in router-interface ve 1, I get this error code, " error- IP routing, vrf, ip policy, route-only, rpf-mode, ip mac or ip tcp mss was configured on ports 1/2/1. How can I resolve this issue? Some context: I up my uplink in port c1 which will eventually connect to my modem but it is connected to a switch right now. I am trying to set up 3 APs and have different VLANS for the family and guests and IOS devices. But I might connect a switch before the AP as I only have one port in my rooms (would I tag them or leave it untagged?). Thanks in Advance.
