It turns out that I need to use an SNMP client on Windows to communicate with a switch and give it a simple command: such as suspending a port to remove the network connection from a specific node.
The pc from which I want to install the SNMP client is a node of the same network, but with privileges.
This is the solution that has occurred to me for my problem:
-To have the power to not allow the network connection to a specific computer in my network from another node. But I'm not sure how the SNMP client in Windows would work. Any ideas?
