Network Access

Which action is performed by a switch port that is enabled for PoE power classification override?

  • A As power usage on a PoE switch port is checked data flow to the connected device is temporarily paused
  • B When a powered device begins drawing power from a PoE switch port, a syslog message is generated
  • C If a switch determines that a device is using less than the minimum configured power, it assumes the device has failed and disconnects it
  • D Should a monitored port exceed the maximum administrative value for power, the port is shut down and err-disabled
Explanation

With Cisco PoE power classification override, the switch can override the IEEE class allocation and monitor actual inline power against the configured administrative limit. If power policing is enabled with the errdisable action and the powered device draws more than the allowed maximum, the switch shuts down PoE on that interface and places the port into an error-disabled state. This is the documented protection behavior for monitored overdraw on a PoE port.
