Analyzing Traffic
NDE Interface Traffic Analysis
The NDE Interface Analysis page enables you to view data collected for individual interfaces on a switch
or router that is exporting Netflow packets to the NAM. The displayed information represents the total
data collected since the collection was created, or since the NAM was restarted. To view the NDE
Interface Analysis page, choose Analyze > Traffic > NDE Interface.
You need to configure the NDE interface capacity to see both the utilization in the charts and the
interface name on the NDE interface list. See NDE Interface Capacity, page 2-63.
You can also give the SNMP RO (or RW) community string to an NDE data source, and then the NAM
will fill up the NDE interface Capacity. Choose Setup > NAM Data Sources to enter the community
string. For more information, see Creating NetFlow Data Sources Using the Web GUI, page 2-23 or
Creating NetFlow Data Sources Using the CLI, page 2-25.
Select an interface from the Interface Selector on the left side of the screen to see traffic in the charts
(see Figure 3-4). Click the arrow icon to the left of the NDE data source name to display all interfaces,
and then select an interface. If the charts show no data, and you see a message “Interface needs to be
selected,” you have not yet chosen an interface.

Once you have chosen the interface, you will see the following charts populated:
• Interface Traffic (Ingress % Utilization and Egress % Utilization)
• Top N Applications - Ingress
