Promiscuous Mode
Jul 2017
This setting caught me out when I was trying to use tcpdump to capture some multicast traffic. Normally, the capture service (in this case tcpdump ) puts the interface in to 'Promiscuous' mode, but I was still not able to capture any multicast traffic.
I used the ESXi web interface to edit the Port Group to enable Promiscuous mode manually.
After this, tcpdump was able to see the incoming multicasts.
