Process to Ignore Packets in Wireshark

In Wireshark, we can ignore captured packets in the “Packet List” pane if some packets are unnecessary. Wireshark will ignore them as if they do not exist in the capture file. The packets which are ignored are displayed with white background and gray foreground, even if they have pre-defined coloring rules already set. When we ignore a packet, its entry disappears from the Packet List, Packet Details, and Packet Bytes. No information is saved in the capture file. They are lost when the capture file is closed.
