is running at 99% usage, and port 1 is prioritized as high, but port 3 is prioritized as low, port 1 is
prioritized to receive power, and port 3 may be denied power. The possible field values are:
– Low — Defines the PoE priority level as low. This is the default level.
– High — Defines the PoE priority level as high.
– Critical — Defines the PoE priority level as Critical. This is the highest PoE priority level.
• Power Consumption — Indicates the amount of power assigned to the powered device connected
to the selected interface. Devices are classified by the powered device, and the classification
information used. The field values are represented in Watts. The possible field values are:
– 0.44 – 12.95 — Indicates that the port is assigned a power consumption level of 0.44 to
12.95 Watts.
– 0.44 – 3.8 — Indicates that the port is assigned a power consumption level of 0.44 to 3.8
Watts.
– 3.84 – 6.49 — Indicates that the port is assigned a power consumption level of 3.84 to 6.49
Watts.
– 6.49 – 12.95 — Indicates that the port is assigned a power consumption level of 6.49 to
12.95 Watts.
• Overload Counter — Indicates the total power overload occurrences.
• Short Counter — Indicates the total power shortage occurrences.
• Denied Counter — Indicates times the powered device was denied power.
• Absent Counter — Indicates the times the power supply was stopped to the powered device
because the powered device was no longer detected.
• Invalid Signature Counter — Indicate the times an invalid signature was received. Signatures are
the means by which the powered device identifies itself to the PSE. Signature are generated during
powered device detection, classification, or maintenance.
• Power Allocation (milliwatts) — Indicates the power allocated to the port. The range is 3000-
15400 milliwatts.
• Mode — Indicates if the port is enabled to work on PoE. The possible field values are:
– On — Indicates the device is delivering power to the interface.
– Off — Indicates the device is not delivering power to the interface.
– Test Fail — Indicates the powered device test has failed. For example, a port could not be
enabled and cannot be used to deliver power to the powered device.
– Testing — Indicates the powered device is being tested. For example, a powered device is
tested to confirm it is receiving power from the power supply.
