Some filters are written here in a general form, and some are made as concrete examples. Here I consider the display filters that are entered in the main window of the program in the top field immediately below the menu and icons of the main functions. Remember that Wireshark has display filters and capture filters.

Also here in the comments I suggest you share the running filters that you often use, as well as interesting finds – I will add them to this list.
