Juniper EX Series User Manual

2. Type any of the following CLI commands:
• show poe controller
• show poe interface
• show poe telemetries
For detailed information about using these CLI commands to monitor PoE power
consumption, see Monitoring PoE Power Consumption (CLI Procedure).
Meaning In the J-Web interface the PoE Monitoring screen is divided into two parts. The top half
of the screen displays real-time data of the power consumed by each PoE-capable
interface and a list of ports that utilize maximum power.
Select a particular interface to view a graph of the power consumed by the selected
interface.
The bottom half of the screen displays telemetry information for interfaces. The Telemetry
Status field displays whether telemetry has been enabled on the interface. Click the
Show Graph button to view a graph of the telemetries. The graph can be based on power
or voltage. To modify telemetry values, click Edit. Specify Interval in minutes, Duration in
hours, and select Log Telemetries to enable telemetry on the selected interface.
