The NM-NAM performs analysis on layers
3-7 on all packets on the NM-NAM
interface. The data source is not broken
down into individual streams like the
VLANs on the NAM-1/2, hence there are
fewer monitoring options

Selecting NM-NAM Data Sources to Configure
Before looking at configuration examples, let’s briefly look at the differences in the NM-NAM configuration. The
basic configuration still applies – you must enable the type of analysis to perform on each data stream. What is
different is that the NM-NAM is not VLAN centric like the NAM-1/2. In fact, when using the NM-NAM, you will not
see any reference to a VLAN. Simply pick the data source and enable the desired analysis. There is no breaking
down of the data sources into individual streams of data like interfaces. The exception to this is the NDE data
sources which can be broken down by NDE devices.
Now let’s take a look at look at enabling data collections on the NM-NAM.
