From the Multicast filtering mode drop-down menu, select Basic, and click OK. 3ad) with Esxi 6. For most ESX use cases, MAC learning is not required as ESX knows exactly which MAC address will be used by a VM. Monitor VSAN VMKernel Port network traffic. I've read that guide but as far as I can tell, vmware should be blocking the multicast VMware recommends configuring the cluster to use NLB multicast mode even though NLB unicast mode should function correctly if you complete these steps. To use IGMP multicast, the network switches must be capable of IGMP snooping. This mode is basically the same as multicast mode, except that the switches can automatically build their MAC address tables in this mode. Physical switches do IGMP snooping in order to know what multicast groups the hosts on a port are interested in. These ESXi hosts are running a Windows Network Load Balancing (NLB) cluster and I have IGMP multicast mode configured. VMware vSphere Networking deep dive - Download as a PDF or view online for free. Symptoms: For redundancy at least two ONTAP virtual machines (VMs) are deployed on different ESXi hosts. An attacker might use this flaw to shut down this server and. 2.
