WLAN Analysis with Wireshark (Frame Section, Part 4)

According to the below screen shot, frame #12, frame length is equal to 353 bytes. When we take the number of 353 and then multiple by 8, the result turns to 2,824 (bits).


In Wireshark, any specific frame(s) can be noted as "Ignore" packets, where the configuration is able to be made under the menu of "Edit --> Ignore/Unignore Packet." The following screen shot should describe this capability.


When a frame is described as "Ignored," it will be dis-selected, then, no further analysis will be made.

Let's take the following illustration as an example. With the Packet Length under Statistics menu, you should be able to see 106,879 as the total packet counts.


However, we have decided to ignore frame 12-14, as shown here. (An ignored packet will be shown with white background and gray foreground.)


With that, the total packet count should be 106,876 (107,879 - 3 = 106,876), as displayed here.


However, under the menu of "Statistics -> Capture File Properties," as shown here, the total captured / displayed packets should remain the same (106,879, in this example).
