# I need to set the custom bandwidth speed for router interface which is provided by Internet Service Provider(ISP) and not to use physical interface speed for my utilization calculation. How can I do this in SapphireIMS?

SapphireIMS supports setting custom bandwidth speed to override physical speed which is discovered through scanners. This helps in calculating interface utilization as per the speed provided by internet service providers. Once you set, utilization value will be calculated against custom speed and all views/reports shown with respect to this speed.

This can be done by navigating to tabs -  
Performance → Select Network or Server → Click on specific device → Select Interface tab → Go to Current Bandwidth widget graph

**Click on Setting icon on right top corner**
