For detailed information about the appropriate description of the various supported CPUs and VMs, refer to Terminology.

Using Wireshark, a tool for analyzing network protocols and connections, the DSC Platform allows the examination of SIGTRAN traffic data. The IMF processes on each Routing CPU can send a copy of the traffic data (MSUs) along with header information to a file on the Routing and Management VMs for analysis (/var/log/packet_capture.pcap). You can then download this file for analysis to a workstation that is running Wireshark.

Note

The file can be obtained using the File Retrieval function in the Web UI. For information about File Retrieval, refer to the appropriate section in the DSC - SP2000 Platform Manager User Guide.

You can either start and stop or set the duration of the packet capture (in seconds).

When the packet capture is started, an alarm is raised (refer to 8402 imfPacketCaptureActive) that this packet capture is in progress and the system performance may be affected. When the packet capture is stopped, the alarm is automatically cleared (refer to 8403 imfPacketCaptureClear).

To allow Wireshark to analyze the IMF header information, a Wireshark plug-in is provided. For information about obtaining and installing this plug-in on your system, refer to Configuring Wireshark.

To configure the IMF packet capture 

  1. From the Main Menu, click IMF.

  2. Click IMF Packet Capture

          
  3. Do one of the following:
    1. Enter the duration of the packet capture (in seconds).

    2. Use the Start or Stop actions to initiate or end the packet capture.

  4. Click Continue.
