In the “Level of detail” section we can make the network capture shown in the lower part with more or less detail, but in most cases what we will do is download the data capture and examine it carefully in programs like Wireshark. In “Packet Length” we will have to put 0 to capture all the frames and not limit by frame size, and in “Count” it is advisable to put 0 to capture all the traffic until we stop it manually, by default it is the value of 100 which could be very little depending on the equipment in question. All application layer protocols make use of specific source and destination ports, for example, if we want to capture HTTP traffic, we will put port 80 and filter by TCP, since it is what the HTTP application layer protocol uses. But it won’t look inside encrypted traffic unless it has a key. So that would be all network traffic on one computer - wired, wifi, USB etc. If the user running it has root/admin privilege to put interfaces into monitor mode, Wirehark can show the traffic. We can also configure the source or destination port if we use TCP and / or UDP, ideal for only capturing the traffic that interests us. Can Wireshark see all network traffic Usually.

If we do not put anything, it will capture all the packets that travel through the interface, without filtering by IP or MAC at all. This option allows us to only capture the traffic that has as its origin or destination a specific IP address or MAC address (if it is directly connected to the same subnet). Other available options are the possibility of choosing the “Host address” option.
