What is trap and close?
Hello,
Does anyone know what "trap and close" is?
If so, what is needed to implement it on a network?
Thank you in advance.

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

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

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