After entering the filter name, you will see only the stp packets.For many years, WinPcap has been recognized as the industry-standard tool for link-layer network access in Windows environments, allowing applications to capture and transmit network packets bypassing the protocol stack, and including kernel-level packet filtering, a network statistics engine and support for remote packet capture. To display only the STP packets from all the captured packets, type stp as shown below. To only show the packets containing a specific protocol, type the protocol name into the “Apply a display filter” field under the toolbar.
