Which option is the default switch port port-security violation mode?
Click on the arrows to vote for the correct answerA. B. C. D.
The default switch port port-security violation mode is "shutdown."
Port security is a feature of Cisco network switches that allows network administrators to restrict the number of devices or users that can connect to a particular switch port. It can help prevent unauthorized access to the network and protect against MAC address flooding attacks.
When port security is enabled on a switch port, the violation mode determines what action the switch takes when a security violation occurs. There are three violation modes available:
Shutdown: This is the default mode. When a security violation occurs (such as when a user tries to connect an unauthorized device to the port), the switch will immediately disable the port, effectively shutting it down. The switch will also send a notification to the network administrator indicating that a security violation has occurred.
Protect: When a security violation occurs, the switch will drop any traffic from the unauthorized device, but the port will remain enabled. The switch will still send a notification to the network administrator.
Restrict: When a security violation occurs, the switch will drop any traffic from the unauthorized device, but it will not disable the port or send a notification to the network administrator. This mode is often used for testing or troubleshooting purposes.
The "shutdown vlan" option is not a valid port-security violation mode. It is actually a command used to shut down a specific VLAN on a switch.
Therefore, the correct answer is A. shutdown.
