Configuring ITM and Top Traffic Using the GUI Integrated Traffic Monitoring

5. Determine the minimum number of minutes that Top Talkers and Top Listeners data is accumulated.

Specify an interval option of 5, 10, and 15 minutes using the drop-down menu. When viewing Top

Traffic data, the current interval displayed will reflect the interval choice at this stage of configuration.

6. Determine and specify whether the Top Traffic will measure traffic by byte count or packet count.

• Top Talkers and Top Listeners measured by byte count display overall bandwidth consumption on

a host-by-host basis. Top Talkers hosts are identified by the source IP address that transmitted the

most data in bytes over a period of time (interval). The Top Listeners hosts are identified by the

destination IP address that received the most data in bytes over an interval.

• Top Talkers and Top Listeners measured by packet count display which hosts generated or received

the highest number of packets over a period of time. Using packet count to monitor hosts can make

it easier to identify the source of problems in cases where a host is infected by a virus, or when a

host is attacking the network with a port scan, sequentially generating large numbers of small

packets. In this case, the overall byte count generated by the host may not be large enough for that

host to show up on the Top Talkers list by byte count, but it would show up on the Top Talkers list

by packet count. The Top Listeners packet count will identify those hosts who have received the

most packets, making it easier to determine if a host is the subject of some sort of malicious traffic,

such as a denial of service attack.

• Monitoring by byte count or packet count are mutually exclusive and must be configured by the

user. The default statistic is number of bytes.

It is important to remember that once Top Traffic is configured, if the interval time is

changed, all data collected at the previous interval setting will be lost.
