style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'">Hello.
I have a voip monitoring application that my team has created. At this
point we are using a SPAN (mirror) port on the switch to listen to the
traffic. Is it possible to use a network tap with winpcap? I
assume that winpcap sees the network as two separate network interfaces.
Do I just need to open both interfaces and then in my software merge the
packets into the same stream? Or is there more to it than
that?<o:p></o:p></SPAN></P>
