Interface speed and bandwidth

Table of contents

Updated: February 18, 2019

Overview

In the Interface details view, there are values for Interface bandwidth and Configured Interface speed.

 

Environment

  • All versions of NPM 

Detail

In the interface details, the Configured Interface Speed is what NPM reads from the device with SNMP during the device discovery, the Interface bandwidth would normally be the same as the Configured Interface speed but the Interface Bandwidth can be manually configured by going to the Edit Interface page.

This is useful if you have a device with as an example a Gigabit interface connected to a 2MB line, you can set the Interface Bandwidth to 2MB which would then adjust the chart displays for the device.
