Network Monitoring Using NAMs

NetFlow as a Data Source

NAM offers a powerful

combination of NetFlow

and RMON monitoring

• Use both RMON and NetFlow to

provide application-level visibility

• Exporting of NetFlow data to the NAM

allows monitoring of multi-layer

switched traffic (L3) on an aggregate

basis

• Use the NAM RMON capability for

detailed analysis of voice traffic,

quality of service, application

response time, and packet capture

and decode

NetFlow as a Data Source

For flexibility, NetFlow data collections can be used to provide coverage of streams not directly accessed by

the NAM. Hence, an important WAN interface that you wish to monitor but the host router cannot accept a

NAM, can be analyzed by enabling NetFlow for the interface and exporting the collection statistics to a NAM.

The NAM provides a more in-depth analysis of the traffic streams than what NetFlow can provide. NetFlow

analysis does, however, provides application visibility by reporting statistics on application usage including

hosts and conversation information for each application.

Before looking at details of the NAM Traffic Analyzer software, let’s first take a look at the different types of

NAMs and the data source used by each.
