We got a great question from a customer last week. They emailed asking us, "How do I use LANGuardian to detect multicast traffic on my

The situation on the customer site was slow performance on the LAN due to a high degree of multicast traffic. In order to resolve this issue, they needed to find out, "What systems are generating multicast traffic and where it is originating from"?.

You just need to run a traffic report with the subnet filter

The following procedure describes the steps to start monitoring Multicast traffic.

  1. Determine the subnet range for Multicast -
  2. Set up a Multicast Report.
  3. In the IP section, click on Top Applications. The IP :: Top Applications report is displayed.
  4. Enter the IP information that you gathered in Step 1 in the IP/Subnet field.
  5. When the report is displayed, click More Actions on the report menu bar and select Save Report.
  6. Enter a name and description for the report, then click Save. The report will be listed in the Custom Reports section.

You can simply drill down into the Multicast traffic and identify the systems that are generating the multicast traffic.

And, of course, please contact us any time if you have any questions about detecting Multicast traffic or indeed any other aspect of network monitoring with LANGuardian.
