Hardware and Software Requirements and Limitations Integrated Traffic Monitoring

Hardware and Software Requirements and Limitations

ITM operates on ADTRAN Operating System (AOS) products that also support RapidRoute. The data

platforms include NetVanta 340, 344, 3130, 3200 (third generation only), 3305, 3430, 3448, 4305, and

5305. The voice products include the Total Access 900(e) Series, the NetVanta 6355, and the

NetVanta 7000 Series.

The ITM feature is available on AOS data products running firmware version 16.1 or later.

The Top Traffic feature is available on AOS data products running firmware version 17.1.1 or later.

Top Traffic web-based graphical information is available on AOS data products running firmware version

17.2.1 or later.

The ITM and Top Traffic (Top Talkers) features are available on AOS voice products running firmware

version A1.1 or later.

External Data Collector

For some networks, ITM can be enhanced by using external data collector. ITM currently employs

Netflow version 9 as an export protocol for maximum operability with external data collectors. External

data collectors provide a place for analyzing traffic flow data, and often contain software that presents the

data in graphical form. Collectors come in both purchased applications and freeware. Commercial

applications include IBM’s Aurora and IdeaData’s Traffic and Security Analysis, and freeware collectors

include NTOP, Flow-Viewer, and Plixer’s Scrutinizer.

ITM Limitations

Using ITM does slightly affect memory and CPU usage on your AOS product. Depending on the amount

of available memory, capturing large amounts of traffic flow data may fill up the flow cache. An increase

in memory or a reduction in data capture (by using sampling, for example) can alleviate this problem.

For a more detailed description of these products, refer to ADTRAN’s website at

www.adtran.com.

It is highly recommended that RapidRoute be enabled on your AOS product to keep ITM

memory and CPU usage to a minimum.
