Verifying PoE Configuration and Status for a Junos Fusion (CLI Procedure)
You can verify the Power over Ethernet (PoE) configuration and status on Junos Fusion.
This topic describes how to verify:
PoE Power Budgets, Consumption, and Mode on Satellite Devices
Purpose
Verify the PoE configuration and status, such as the PoE power budget, total PoE power consumption, power management mode, and the supported PoE standard.
Action
Enter the following command:
user@aggregation-device> show poe controller
Controller Maximum Power Guard Management Status Lldp index power consumption band Priority 100 925.00W 0.00W 19W Class AT_MODE Disabled 120 125.00W 6.08W 19W Class AT_MODE Disabled
Meaning
Satellite device 100 has a PoE power budget of 925 W, of which 0 W were being used by the PoE extended ports at the time the command was executed. The Guard band field shows that 19 W of power is reserved out of the PoE power budget to protect against spikes in power demand. The power management mode is class. The PoE ports on the switch support PoE+ (IEEE 802.3at).

PoE Interface Configuration and Status
Purpose
Verify that PoE interfaces are enabled and set to the correct maximum power and priority settings. Also verify current operational status and power consumption.
Action
To view configuration and status for all PoE interfaces, enter:

<additional output removed for brevity>To view configuration and status for a single PoE interface, enter:
user@switch> show poe interface ge-120/0/0 PoE interface status: PoE interface : ge-120/0/0 Administrative status : Enabled Operational status : ON Power limit on the interface : 7.0W Priority : Low Power consumed : 3.9W Class of power device : 2 PoE Mode : 802.3at
Meaning
The command output shows the status and configuration of interfaces. For example, the interface 120/0/0 is administratively enabled. Its operational status is ON; that is, the interface is currently delivering power to a connected powered device. The maximum power allocated to the interface is 7.0 W. The interface has a low PoE power priority. At the time the command was executed, the powered device was consuming 3.9 W. The class of the powered device is class 2. If the PoE power management mode is class, the class of the powered device determines the maximum power allocated to the interface, which is 7 W in the case of class 2 devices.
The PoE Mode field indicates that the interface supports IEEE 802.3at (PoE+).
