Configure a site-to-site speed test to measure download and upload speeds between source and destination devices.

This task allows you to measure the network performance between two devices by testing the download and upload speeds of their tunnel interfaces.

Site-to-site speed tests help you verify network performance and troubleshoot connectivity issues between devices in your network. The test measures bandwidth utilization and displays results alongside configured circuit bandwidths for comparison.

Before you begin

Ensure that Data Stream is enabled under Administration > Settings in Cisco SD-WAN Manager.

Follow these steps to run a site-to-site speed test:

Procedure

  1. From the Cisco SD-WAN Manager menu, choose Monitor > Devices.

    Cisco vManage Release 20.6.1 and earlier: From the Cisco SD-WAN Manager menu, choose Monitor > Network.

  2. To choose a device, click the device name in the Hostname column.

  3. Click Troubleshooting in the left pane.

  4. In the Connectivity area, click Speed Test.

  5. Specify the following parameters:

    • Source Circuit: From the drop-down list, choose the color of the tunnel interface on the local device.

    • Destination Device: From the drop-down list, choose the remote device by its device name and system IP address.

    • Destination Circuit: From the drop-down list, choose the color of the tunnel interface on the remote device.

  6. Click Start Test.

The right pane shows the results of the speed test, the download, and upload speed between the source and destination. The download speed shows the speed from the destination to the source, and the upload speed shows the speed from the source to the destination in Mbps. The configured downstream and upstream bandwidths for the circuit are also displayed.

When a speed test completes, the test results are added to the table in the lower part of the right pane.

From Cisco vManage Release 20.10.1, the Speed Test option is also accessible as follows:

  • On the Monitor > Devices page, click … adjacent to the device name and choose Speed Test.

  • On the Monitor > Applications page, click … adjacent to the application name and choose Speed Test.

  • On the Site Topology page, click a device name, and then click Speed Test in the right navigation pane.
