Security Configuration of Core Switch Ports
This complete port security configuration guide covers sticky MAC address learning, violation modes, troubleshooting err-disabled ports, and advanced security scenarios that networking professionals use daily. If you try to set the maximum value to a number less than the number of secure addresses already configured on an interface, the command is rejected. To understand port security, you should be familiar with how switches learn MAC addresses. Let's. To block unauthorized access to switch ports, switches support a feature called port security. This tutorial explains. In MAC-flooding, an attacker can connect a laptop into an empty Switch port or empty RJ45 wall socket, and he can use hacking tools to generate millions of Ethernet frames with fake source MAC addresses and send them to the switch interface.
