There is a good chance...
In that case, could you give me more information
about firewalls, network protection, and VLANs.

No, it has nothing to do with firewalls. It's much simpler and older.
The trap and close is a mechanism that locks a switch or ethernet hub port when it has been connected to a device with an incorrect MAC address (ISO layer No. 2). Specifically, on a wall socket, there is only one device that is allowed. If another device is plugged in, the socket is locked and cannot be used until a network administrator unlocks it.

I know this as port-security, I've never seen it called trap and close.

So there are the two names.
Port-security, I think it’s a Cisco designation.

Indeed, it's under Cisco, I had encountered the function at Nortel, I believe, but I don't remember the exact name.
No, at Nortel, it's port security as well.
And at 3Com too: https://www.hpe.com/h41271/404D.aspx?cc=us&ll=en&url=http://domainredirects.ext.hpe.com/support.3com.com/infodeli/tools/switches/4400/dha1720-3aaa7/htmcli/securitynetworkaccessportsecurity.htm
