      no, are 3 switch 24 port unmanaged dlink 100Mbit model DES-1024D.

      i see also that if there is a multicast task in progress, the dhcp server don’t serve the clients

        You can try to multicast 3 machines, to find the computer wich run slowly on multicast.

          i just tryed with only one pc in multicast mode: runs at 130Mbyte/min

          Same pc in unicast runs at 1,2Gbyte/min so i think that multicast module is buggly

                With 1.2 and svn I had these problems due to Cisco configuration, not a problem with FoG.

                You can’t compare Unicast and Multicast, they don’t use the same protocole.

                Do you have another model of 100Mb switch ?

                    You can try SVN version, but I think it’s a problem with the switch…

                      It definitely sounds like an issue with the switch.

                      Is there a way you could try a cross over cable and temporary dhcp server on your fog server? Do things work better this way?

                        Personally I only every use Unicast, it’s faster, it’s more reliable, and it doesn’t bring my DHCP Server down.

                        Is there a particular reason you want to multicast these?

                        If it were my environment, I wouldn’t be multicasting on this equipment.
