Refer to the following figure. You received a call that a port is no longer active. The port has port security configured on it. What is the problem?

The default configuration for port security results in an access violation of shutdown. When a port security violation occurs, the port will be shut down in an err-disable status. Because the port is in an err-disabled state, the figure does not support the theory that a port has been administratively shut down. The figure also does not support the theory that the port has bad wiring. You cannot tell from the output in the figure that the port is configured as a trunk or access link, but neither will place the port into an err-disabled state.
