32.3.3 Example of Viewing a Packet Capture File
Here is an example of a packet capture file viewed in the Wireshark packet analyzer. Notice that the
size of frame 15 on the wire is 1514 bytes while the captured size is only 1500 bytes. The NXC truncated
the frame because the capture screen’s Number Of Bytes To Capture (Per Packet) field was set to 1500
bytes.
