What does the OtherTCP sensor include?



I am using the NetFlow sensor to monitor my Cisco router, running NetFlow v5 with all channels active and set to Detail. I am seeing a lot of OtherTCP traffic. What protocols does OtherTCP include?

In order to discern what further filters could apply to this data, you can turn on the Log Stream Data to Disk (for Debugging) option under the NetFlow Specific Settings of the sensor. This will generate a log file including detailed information about the flow. Using this information it is possible to discern what further filtering parameters can be included to break up the flow information in order to provide more specific packet information.

OtherTCP stands for TCP traffic not belonging to one of the other channel definitions in use.
