Monitoring PoE

Purpose

Use the monitoring functionality to view real-time data of the power consumed by each PoE interface, and to enable and configure telemetry values. When telemetry is enabled, the software measures the power consumed by each interface and stores the data for future reference.

Note: If you are configuring a Virtual Chassis, the PoE monitoring option is displayed if any member of the Virtual Chassis supports PoE, even if the Virtual Chassis master does not support PoE.

Action

To monitor PoE using the J-Web interface, select Monitor > Power over Ethernet.

To monitor PoE power consumption with CLI commands in the CLI Terminal in the J-Web interface:

  1. Select Troubleshoot > CLI Terminal.
  2. Type a CLI command:

For detailed information about using these CLI commands to monitor PoE power consumption, see Monitoring PoE Power Consumption (CLI Procedure) in the EX Series documentation at https://www.juniper.net/techpubs.

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.
