Scenario 2
Configuring Interfaces as Data Sources
When local Interfaces are enabled
as a data source, the NM-NAM will
automatically interact with the
router to:
Enable NetFlow Data Export
(NDE) on the router Interfaces
Set itself as the destination for
NDE
Provides Application, Host, and
Conversation data with no further
set-up

Configuring Interfaces as Data Sources
By default the NM-NAM will query the MIB-II parameters on the host router to retrieve basic statistics for
each interface (much like the mini-RMON stats on the NAM-1/2). Typically, viewing the interface utilization
stats would help determine which traffic to forward to the NM-NAM for more depth analysis. To provide you
with some deeper analysis prior to forwarding the traffic via CEF to the NM-NAM, the NM-NAM can configure
the router to forward interface traffic via NetFlow to itself for application, hosts, and conversation statistical
analysis. Dean uses the following steps to configure this feature:
Step 1. Click Setup > Data Sources > Interfaces. The Interfaces dialog box is displayed showing a list
of all interfaces on the host router.
Step 2. Enable the desired interfaces in which to forward NetFlow traffic to the NM-NAM and click
Apply.
The NM-NAM will now configure the host router to enable NetFlow on the selected interfaces and set itself
as the destination.
