Dashboard Interface View

The Interface View tab displays information on all interfaces from which NetFlow exports are received.

The default Router List shows all the routers and interfaces from which NetFlow exports have been received so far, along with specific details about each interface. The default view shows the first router's interfaces alone. The interface names can be sorted based on usage. The remaining routers' interfaces are hidden. Click the [Show All] link to display all routers' interfaces on the Dashboard. Click the [Hide All] link to hide all interfaces and show only the router names in the Router List.

You can set filters on the Dashboard view to display only those interfaces whose incoming or outgoing traffic values exceed a specified percentage value. Click the [Filter] link to specify minimum percentage values for IN or OUT traffic. Click the Set button for the changes to take effect. The filter settings are then displayed beside the [Filter] link. Click the icon at any time to clear the filter settings and display all interfaces on the Dashboard again.

	Click this icon to hide the interfaces corresponding to the router
(before Router Name)	Click this icon to change the display name of the device
(before Interface Name)	Click this icon before the interface name to change the display name of the interface, or its link speed( IN and OUT (in bps)).
(near Refresh)	Click this icon, to set the time period for refreshing the page contents.
	Click this link to troubleshoot an interface. You can troubleshoot only one interface at a time. Note: Troubleshooting results are shown directly from raw data. Hence results depend on the raw data retention time period set in Settings
	Indicates that NBAR report is available for the interface
	Click on this icon to have a preview of the traffic graphs without drilling down in to each interface
	Indicates that CBQoS report is available for the interface

The Interface Name column lists all the interfaces on a discovered device. Click on an interface to view the traffic details for that interface.

The Status column indicates the current status of that interface.

Icon	Description
	The Status of the interface is unknown and no flows have been received for the past 10 minutes. The interface is not responding to SNMP requests.
	The interface is responding to SNMP requests and the link is up, but no flows have been received for the past ten minutes.
	The link is up, and flows are being received.
