Hi,
We are having some issues getting communication between multiple virtual devices on our vSphere 3.5 server.
We had our system setup running on a single virtual network attached to one virtual port of type flexible NIC. Communication was via UDP unicast packets and was successful. However when we moved to send the UDP via multicast, the traffic stopped.
We changed the NIC type to E1000 and multicast traffic started, however now we cannot get unicast data between the two devices. In fact we cannot even ping the devices from each other. However the strange thing is we can ping the devices from the external network.
The devices themselves are vxWorks 5.5. PC devices running on the same virtual server seem to be OK and we can ping them, so it seems to be something with the NIC and the interpreted ethernet device type.
Any suggestions on possible fixes or other investigation steps gratefully accepted
