Cisco Switch Port Security is a feature that allows network administrators to secure Ethernet switch ports by limiting the number of devices that can access the network through a particular port. This helps prevent unauthorized devices from gaining network access and enhances overall network security. Here’s an overview of how Cisco Switch Port Security works and its key configurations:
Switch Port Security supports three violation modes: Shutdown (default): The port is put into an error-disabled state if a security violation occurs, requiring administrative intervention to re-enable.
Here are the key components and features of Cisco Switch Port Security:
MAC Address Limiting: You can configure a switch port to allow connections only from a specific number of MAC addresses. This prevents unauthorized devices from connecting through that port.
MAC Address Sticky: This feature allows the switch to dynamically learn the MAC addresses of devices connected to the port and then save them in the running configuration. This simplifies management because you don't have to manually configure each allowed MAC address.
Violation Modes: If a violation occurs (e.g., a new MAC address tries to connect), you can specify how the switch responds: Protect: Drop packets from unauthorized MAC addresses. Restrict: Drop packets and generate a log message. Shutdown: Put the port into an error-disabled state.

Switch Port Security supports three violation modes:
Shutdown (default): The port is put into an error-disabled state if a security violation occurs, requiring administrative intervention to re-enable.
Restrict: Traffic from unauthorized MAC addresses is dropped, but the port remains operational. Cyber Security Projects For Final Year
Protect: Similar to restrict mode, but SNMP traps are generated instead of dropping traffic.
