7.1 Why do we use filters?
TAP CURIOUS records all Ethernet frames transmitted on the connected network
line. TAP sends the Ethernet frames to the connected PC via the "Uplink to PC"
port. Wireshark writes these frames to the main memory (RAM) on your PC.
This not only makes it more difficult for your to monitor data, it can also overload
the main memory and cause your PC to crash.
To prevent this from happening, you can set various filters for each probe port.
These filters check whether the incoming frame has the properties you defined in
the filter settings. If the data have these properties, they will be written to the main
memory on your PC. If the data do not have these properties, they will be ignored.
The following filter elements are available:
Status filter
The status filter enables you to filter properties such as the receiving time or the
status of a frame. This filter is applied to the 20 bytes, which are additionally
transmitted to the standard frame.
Segment filter
You can use the segment filter to filter data for parity or disparity within the frame.
There are 16 words (4 bytes) available, and these can be checked in succession.
