This switch I got has a web GUI and supports VLANs. But it's marked as 'Unmanaged Pro' on the box? Have I had a misunderstanding of the definition of a managed switch all this time?

I got my first managed switch at the recommendation of a friend. But when it arrived, I initially freaked out because, as you can see, it has 'Unmanaged Pro' plastered on the front.

But you'll also notice it notes a web management interface in the bottom corner. A switch wouldn't have a web GUI unless it was managed, right?

But it definitely has multiple VLAN config panels and I can tag ports, etc.

Have I had a misunderstanding of what 'managed' means all this time?
