If a power device exceeds the PoE cutoff on a powered interface and power policing is enabled, the interface remains in an error-disabled state until which event occurs?

• A. 300 seconds
• B. Until it is manually reset with the shutdown and no shutdown commands
• C. 30 seconds
• D. 86400 seconds

Answer: (B)

PoE power policing protects the switch by disabling a port when a connected device tries to draw more power than allowed. When this condition occurs, the port is put into an error-disabled state. It won’t automatically recover after a timer unless you’ve configured errdisable recovery for this specific cause. In the standard setup, the port remains disabled until you clear that fault by administratively resetting the interface, which is done by issuing shutdown on the interface and then no shutdown to re-enable it. This manual reset is why the correct event is the administrative reset sequence.
