What occurs when a switch port violates its configured security policy?

When a switch port violates its configured security policy, the typical behavior is to either shut down the port or invoke a secure action to mitigate the risk posed by the violation. This ensures the integrity and security of the network by preventing unauthorized access or other potential security issues.

The security policies defined on the switch may include settings such as limiting the number of MAC addresses that can be learned on a port or enforcing access control lists. Upon a violation, the switch can either disable the port, effectively preventing any further unauthorized access, or take corrective measures to secure the port, such as applying a specific security action that protects the network while continuing to monitor the traffic.

This automatic response is crucial in maintaining the overall security posture of the network and preventing potential breaches. Other options do not align with standard network behavior for handling security violations. For example, automatic reconfiguration of the port or failing to respond to a violation would pose significant risks to network security, while resetting all connected devices would not be a practical or effective solution to handling security breaches on a specific port.
