Hi,
I have been struggling with the same problem recently in a similar setup, and I also have found the mentioned MAC learning filter VIB, but I wanted to ask few questions before I go for it.
It is not clear to me, that after I install the VIB, on which vm network ports should I enable the dvfilter? I suppose those VM-ports have to be filter enabled which are connected to a port group with promiscuous mode enabled, right?
Another point is, that this MAC filter never forgets. Once a MAC is stored in the MAC table, it remains there for good(!?), which a little bit worries me, since if the MAC table is full, the filter would no longer be capable to prevent the packet flood. But on the other side, I personally do not know how many MACs can be stored for a given port in the MAC table.
Do you happen to have any experience with that, or a workaround whether the MAC table can be emptied somehow manually once it gets full?
Thanks,
Leva
