Output Fields

Table 1 lists the output fields for the show poe controller command. Output fields are listed in the approximate order in which they appear.

Table 1: show poe controller Output Fields

Field Name

Field Description

Controller index

PoE controller number:

  • 0 for EX2200, EX3200, standalone EX3300, standalone EX4200 switches, standalone EX4300 switches, and ACX2000 routers.

  • Member ID for switches in an EX3300 Virtual Chassis, EX4200 Virtual Chassis, EX4300 Virtual Chassis, a mixed EX4200 and EX4500 Virtual Chassis.

  • Slot number for line cards with a PoE controller in an EX6200 or EX8200 switch.

Maximum power

The maximum PoE power consumption for the switch or line card. This is the total amount of power available to the PoE controller to allocate to the PoE ports.

Power consumption

Total amount of power being consumed by the PoE ports at the time the command is executed. This value, which represents actual power consumption, cannot exceed the value for Maximum power.

Guard Band

Amount of power that has been placed in reserve for power demand spikes and that cannot be allocated to a PoE interface.


Power management mode: class or static or high-power.


The mode high-power is available on only ACX2000 routers.


Status of the PoE controller:

  • AF_ENHANCE—Controller supports enhanced PoE. The maximum power per PoE port is 18.6 W in static mode (15.4 W in class mode).

  • DEVICE FAIL—Software download to the controller has failed or the PoE controller is not initialized because of a hardware failure.

  • DOWNLOAD_INIT—Software download to the controller is in the initial phase.

  • AF_MODE—Controller supports standard IEEE 802.3af. The maximum power per PoE port is 15.4 W.

  • AT/AF COMBO—Controller supports a mix of standard IEEE 802.3af and IEEE 802.3at (PoE+) ports. The maximum power per port is 30 W for IEEE 802.3at (PoE+) ports and 15.4 W for the IEEE 802.3af ports.

  • AT_MODE—Controller supports IEEE 802.3at (PoE+). The maximum power per PoE port is 30 W.

  • BT_MODE—Controller supports standard IEEE 802.3bt (PoE). The maximum power per PoE port is 90 W.

  • SW_DOWNLOAD (n%)—Software download to the controller is in progress.

Lldp Priority

Link Layer Discovery Protocol (LLDP) priority operating state. The state can be Enabled or Disabled.

LLDP priority enables the PoE controller to assign interfaces the power priority provided by the connected powered device by using LLDP power negotiation rather than the power priority configured on the switch interface.
