Multicast traffic specially the one generated by Microsoft's NLB Cluster can flood the network even if it is switched network. Network engineers will often feel the switches acting like a classic hub completely defeating the purpose of switched networks. Microsoft intentially did this in their NLB Cluster by design to achieve the load balancing or express delivery or response to network traffic dealt by their load balancers. In order to track or detect symptoms you will have to trace network packets across network from any port. This can be done using Wireshark on Windows and Snoop on Solaris Unix systems. Packet trace will usually be carried out on one of the network interface connected to VLAN or network in question. In below example we are using Unix snoop command but we would also use other commands to determine what is required. $ bash # access the Bash Shell $ ifconfig -a # list the interface details and write down the interface you want to investigate.
