Explanation:
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.
