Edit Interface Properties

If nominal network interface speed used to calculate bandwidth capacity utilization is incorrect or not populated at the device's management object, you can define a custom speed using the Edit Interface Properties dialog.

Hide and Show Interfaces and Define Total Network Bandwidth (for Calculation Purposes)

1. Select an interface from the Interfaces list window.

   The Flow Interface dialog displays.

   • Hide this interface from the NTA Home page and related configuration properties. Hides the selected interface from the Network Traffic Analysis reports and dashboards. This enables you to display only the interfaces relevant to your bandwidth monitoring objectives.

   Note: Null(0) interface names are hidden by default because they are not a true source interface. Null(0) interfaces show traffic that a router has dropped or traffic that a router has generated. In both cases the ifIndex = 0 and as a default convention we name an interface = Null because the interface is non existent. If you want Null(0) interface information to display as a source interface, uncheck the Hide this interface from the NTA Home page and related configuration properties option.

   • Specify a custom speed for this interface. Click this check box to enable the In and Out text boxes.
   • In and Out. Define the speed of each interface, which is used to calculate bandwidth capacity as a percentage of the total interface speed. Enter the upper limit of the interface in bps (bits per second). Common interface speeds expressed in bps are:
     • 1 Gbps = 1,000,000,000 bps
     • 100 Mbps = 100,000,000 bps
     • 10 Mbps = 10,000,000 bps
2. Click Save to save your settings.
