Configuration Overview
Verify that Voice/RTP Stream
Traffic is being gathered
After the NAM Traffic Analyzer is
started, Voice/RTP stream traffic
will automatically start being
monitored. The NAM enables you
to monitor all RTP stream traffic
among all SPANed traffic, without
having to know the signalling traffic
used in negotiating the RTP
channels.
This will start automatically after
you turn on the NAM.
Analyze > Media > RTP
Streams
or
Analyze > Media > Voice
Call Statistics.
See Voice Signaling/RTP
Stream Monitoring,
page 2-2
Set up the System Time You will need to set up the System
Time correctly; if you do not have
the time synchronized, then you
will see either incorrect or no data.

Configure NDE Data Export The NAM as a producer of NDE
(NetFlow Data Export) packets is a
new feature for NAM Traffic
Analyzer 5.0. The NAM's new
functionality of NDE is part of its
new NBI.
The NAM sends out NDE packets
only in NDE v9 format.

Configure sites A site is a collection of hosts
(network endpoints) partitioned
into views that help you monitor
traffic and troubleshoot problems.
If you want to limit the view of your
network data to a specific city, a
specific building, or even a specific
floor of a building, you can use the
Sites function.
We recommend that sites are
configured using prefix-based
subnets instead of based on data
source.
Setup > Network > Sites.See Sites, page 2-58.
Define Alarms and Thresholds Alarms are predefined conditions
based on a rising data threshold, a
falling data threshold, or both. You
can choose for what types of events
you want the NAM to notify you,
and how you want to be notified.
Alarms that will be used for
Thresholds should be created first,
then then the Thresholds created
second.
