[Winpcap-users] Problem with WinPcap capture with Jumbo frames

[David Chang]

Did you set your 'snaplen' (in pcap_open_live) to 65536?

  Hi WinPcap users,

  I've used winpcap library in my application to capture TCP/IP packets and extract DICOM info from those packets.

   

  It looks like the Winpcap is only able to capture "normal" size ethernet frames(1600 bytes) and not jumbo or super jumbo frames(e.g. 16kb). 

  Maybe the default setting of WinPCap is to capture only normal size frames?

   

  Can we configure ethernet frame size in WinPCap?

  We are missing DICOM data in case of Jumbo frames in Fast gigabit Ethernet.

   

  Kind regards,
