Description This article describes a specific use case for modifying the Interface Bandwidth Graph display from Gbps to Mbps or Kbps in FortiGate.
Scope FortiGate.
Solution

Changing the interface bandwidth graph from Gbps to Mbps or Kbps requires making the following adjustments in the port interface settings.

 

For example, the configuration of the port 15 interface is shown below:

The above configuration shows estimated-upstream-bandwidth 10000000, which is approximately 9765.625 Mbps.

 

  • estimated-upstream-bandwidth Estimated maximum upstream bandwidth (kbps). Used to estimate link utilization.
  • estimated-downstream-bandwidth Estimated maximum downstream bandwidth (kbps). Used to estimate link utilization.

The Interface Bandwidth Graph shown below displays data in Gbps.

To reflect accurate values, the configured estimated bandwidth for port15 must be removed or set according to the actual bandwidth provided by the ISP, using the settings below to change to 100 Mbps.

 

config system interface

    edit "port15"

        set estimated-upstream-bandwidth 102400

        set estimated-downstream-bandwidth 102400

    next

end

 

Similarly, conversion from Mbps to Kbps can be performed using the same method.

 

Referred to the following Fortinet documentation for guidance on adding the FortiView Application Bandwidth widget to the dashboard:

FortiView Application Bandwidth Widget – FortiOS 7.0

 

Followed the documented steps to successfully add the widget to the dashboard for monitoring real-time bandwidth usage by application.
