Is it true that beacon probes are sent with a source MAC address of the virtual MAC of the physical ESXi NIC? Our networking team is seeing MACFLAP log messages on our switches because the same source MAC addresses (virtual MACs of our physical ESXi NICs) are sending packets to multiple VLANs (appears to be every VLAN that the host is running a VM in, as noted here). Etherchannel is not enabled on our switches. Thoughts?
