Displaying inline power statistics

Port

Displays the stack port identification of the port as stack#/slot#/port#.

State: Admin

Specifies whether PoE has been enabled on the port, using one of the following values:

• ON --The inline power command was issued on the port.
• OFF --The inline power command has not been issued on the port.

State: Oper

Displays the status of inline power on the port, using one of the following values:

• ON --The PoE power supply is delivering inline power to the powered device.
• OFF --The PoE power supply is not delivering inline power to the powered device.
• DENIED --The port is in standby mode waiting for power because currently there is not enough available power for the port.

Power (mWatts) Consumed

Displays the amount of current (milliwatts) the powered device is consuming.

Power (mWatts) Allocated

Displays the amount of current (milliwatts) allocated to the port. This value is either the default or configured maximum power level, or the power class that was automatically detected.

PD Type

Displays the type of powered device connected to the port. This value can be one of the following:

• 802.3at --The PD connected to this port is 802.3at-compliant.
• 802.3af --The PD connected to this port is 802.3af-compliant.
• LEGACY --The powered device connected to this port is a legacy product (not 802.3af-compliant).
• n/a-- One of the following is true:
  • The device connected to this port is a non-powered device.
  • No device is connected to this port.
  • The port is in standby or denied mode (waiting for power).

PD Class

Displays the maximum amount of power received by a powered device. This value can be one of the following:

• Class1 --Receives 4 watts maximum.
• Class2 --Receives 7 watts maximum.
• Class3 --Receives 15.4 watts maximum.
• Class 4 --Receives 30 watts maximum.
• n/a --The device attached to the port cannot advertise its class.

Priority

Displays the inline power priority of the port, which determines the order in which the port receives power while in standby mode (waiting for power). Ports with a higher priority receive power before ports with a low priority. The value of priority can be one of the following:

• 1 --Critical priority
• 2 --High priority
• 3 --Low priority

Fault Error

Displays the fault or error that occurred on the port, if applicable. Otherwise, n/a is displayed. The value can be one of the following:

• critical temperature --The PoE chip temperature limit rose above the safe operating level, thereby powering down the port.
• detection failed --The port failed capacitor detection (legacy PD detection) because of a discharged capacitor. This can occur when connecting a non-PD on the port.
• detection failed --The port failed capacitor detection (legacy PD detection) because of an out-of-range capacitor value. This can occur when connecting a non-PD on the port.
• internal h/w fault --A hardware problem has hindered port operation.
• lack of power --The port has shut down due to lack of power.
• main supply voltage high --The voltage was higher than the maximum voltage limit, thereby tripping the port.
• main supply voltage low --The voltage was lower than the minimum voltage limit, thereby tripping the port.
• overload state --The PD consumed more power than the maximum limit configured on the port, based on the default configuration, user configuration, or CDP configuration.
• over temperature --The port temperature rose above the temperature limit, thereby powering down the port.
• PD DC fault --A succession of underload and overload states, or a PDDC/DC fault, caused the port to shutdown.
• short circuit --A short circuit was detected on the port delivering power.
• underload state --The PD consumes less power than the minimum limit specified in the 802.3af standard.
• voltage applied from ext src --The port failed capacitor detection (legacy PD detection) because the voltage applied to the port was from an external source.
