Interface speed on unmanaged interface
You must enter the speed for unmanaged interfaces. Unlike managed interfaces that SolarWinds NPM recognizes, SolarWinds NPM cannot get this information from unmanaged interfaces which it does not recognize. The documentation of your device or your Internet service provider can give more information on determining the speed of an unmanaged interface.
SolarWinds NTA uses the unmanaged interface speed to determine the percentage of resource utilization. Entering an accurate interface speed ensures the correct display of SolarWinds NTA resources. With this information, you can determine the most efficient use of resources.
