If you want to prevent let's say people connecting through an unmanaged switch to your access port, the best thing to do is to configure port security. You can also configure the maximum number of secure MAC addresses for the port (default is 1) using switchport. Port isolation allows a network administrator to prevent traffic from being sent between isolated ports. This article outlines how to configure isolated ports, as. Port Isolation restricts communication between specific ports on the same switch. They can still communicate with non-isolated ports. This proactive measure helps prevent unauthorized or potentially harmful devices from accessing the network, safeguarding sensitive.
