Which command used to verify port security can be used to determine if the port has been disabled by a port security violation?

A. show running-config

B. show port-security violations

C. show port-security interface interface#

D. debug mac-address table

Solution

Answer: B. show port-security violations

show port-security violations command used to verify port security can be used to determine if the port has been disabled by a port security violation.

There are two types of violation modes these are optional though.

1. restrict

2. shutdown

restrict: A port security violation restricts data and causes the SecurityViolation counter to increment and send an SNMP trap notification.
shutdown: The interface is error-disabled when a security violation occurs.
