Which action is taken by switch port enabled for PoE power (CCNA 200-301)
Which action is taken by switch port enabled for PoE power classification override?
A) If a monitored port exceeds the maximum administrative value for power, the port is shutdown and err-disabled.
B) When a powered device begins drawing power from a PoE switch port, a syslog message is generated.
C) As power usage on a PoE switch port is checked, data flow to the connected device is temporarily paused.
D) If a switch determines that a device is using less than the minimum configured power, it assumes the device has failed and disconnects it.
Solution
Correct answer: A) If a monitored port exceeds the maximum administrative value for power, the port is shutdown and err-disabled.
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.
