Switch Port PoE Power Classification Override

A

PoE monitoring and policing compares the power consumption on ports with the administrative maximum value (either a configured maximum value or the port's default value). If the power consumption on a monitored port exceeds the administrative maximum value, the following actions occur:

- A syslog message is issued.

- The monitored port is shut down and error-disabled.

- The allocated power is freed.

When a switch port is enabled for PoE (Power over Ethernet) power classification override, it means that the switch is configured to ignore the power consumption information provided by the connected device and instead allocate a fixed amount of power to the port. This override is typically used in situations where the connected device does not provide accurate power consumption information, or where the administrator wants to allocate a specific amount of power to the port.

Answer A is incorrect because if a monitored port exceeds the maximum administrative value for power, the switch will not shut down the port and err-disabled it when the port is enabled for PoE power classification override. Instead, the switch will allocate the maximum power allowed for that port regardless of the actual power consumption of the connected device.

Answer B is also incorrect because when a powered device begins drawing power from a PoE switch port, a syslog message is generated regardless of whether the port is enabled for PoE power classification override or not.

Answer C is also incorrect because when power usage on a PoE switch port is checked, data flow to the connected device is not temporarily paused, regardless of whether the port is enabled for PoE power classification override or not.

Answer D is also incorrect because if a switch determines that a device is using less than the minimum configured power, it will not assume the device has failed and disconnect it when the port is enabled for PoE power classification override. Instead, the switch will allocate the minimum configured power to the port regardless of the actual power consumption of the connected device.

In summary, when a switch port is enabled for PoE power classification override, the switch ignores the power consumption information provided by the connected device and instead allocates a fixed amount of power to the port. None of the given answers accurately describe the action taken by the switch when this override is enabled.
