Wait, so it doesn't open right after EAP? That's surprising!

I feel like the answer might involve the RADIUS packet exchange, but I can't recall the specifics about Vendor Specific Attributes and their timing.

I’m a bit confused about the role of the Uncontrolled Port. Does it really open immediately after EAP authentication, or is there more to it?

I think I came across a similar question where the 4-Way Handshake was mentioned. Could it be related to why the Controlled Port remains blocked?

I remember studying that the Controlled Port is supposed to stay blocked until certain conditions are met, but I’m not entirely sure which ones.
