[Winpcap-users] Why Winpcap is not wokring with Cisco Switch?

[Gianluca Varenni]

Wireshark/ethereal uses winpcap to capture packets, so it doesn't seem a 
problem strictly related to winpcap. Can you please send me a small capture 
file done with wireshark ethereal showing the packets in both the 
directions?

Have a nice day
GV
