Question How do you undo making a port a trunk port on a Dell 5324 switch?

[Red Squirrel]

I want to convert a port to a regular access port and just assign it a vlan as I'm repurposing an old switch for lab use, but when I try to do it I just get an error "port belongs to multiple vlan". How do I unassign it? I tried

no switchport trunk allowed vlan add 2

(While in the interface)

But it just says unrecognized command.

I've been working with switches for decades but first time I run into this. Normally it just lets me do it. Any ideas?

I gave in and just erased the start file and configured it from scratch. Was a basic config anyway.

Sometimes it be like that. I couldn't even get vlans working on the Dell switch I had been using.
