Operating Status Operating state of a PoE interface
■ off: PoE is disabled.
■ on: Power is supplied for a PoE interface normally.
■ power lack: The guaranteed remaining power of the PSE is not high
enough to supply power for a critical PoE interface.
■ power-deny: The PSE refuses to supply power. The power required by
the powered device (PD) is higher than the configured power.
■ power-itself: The external equipment is supplying power for itself.
■ power-limit: The PSE is supplying a limited power. The power required
by the PD is higher than the configured power and the PSE still supplies
the configured power.
Different models of device support different operating states.
IEEE class PD power class stipulated by IEEE
Detection Status Power detection state of a PoE interface:
■ disabled: The PoE function is disabled.
■ searching: The PoE interface is searching for the PD.
■ delivering-power: The PoE interface is supplying power for the PD.
■ fault: There is a fault defined in 802.3af.
■ test: The PoE interface is under test.
■ There is a fault other than defined in 802.3af.
■ pd-disconnect: The PD is disconnected.
