WAN Edge Testing Tools

Follow these steps to add Juniper Mist™ testing tools to your troubleshooting process.

The Juniper Mist portal provides testing tools that play crucial roles in maintaining network health and diagnosing issues. You can use the tools to:

  • Identify network bottlenecks, latency, and packet loss.
  • Check connectivity and measuring round-trip time.
  • Identify the path taken by network traffic from source to destination for a specific application.
  • Monitor BGP peering status and troubleshoot connectivity issues.

To use WAN Edge testing tools:

Finding the WAN Edge Testing Tools

After you've selected a WAN Edge device on the WAN Edges page, you'll find Testing Tools in the Utilties menu.

Location of Utilities Menu and Testing Tools Option
