Hello,

If someone can explain me if is there something i'm missing:

I have a Catalyst 2950, a Catalyst 2960 and two PCs (one multicast server and one multicast receiver).

For the first test :

               one Catalyst 2950 and two PCs

                             Group multicast= 234.56.78.90     ======> mac multicast = 0100.5e38.4e5a

                              Sender connected to port fast 0/10

                              Receiver connected to port fast 0/8

                              2950 configuration:

                                          default config +

                                        no ip igmp snooping

                                        mac address-table static 0100.5e38.4e5a vlan 1 interface GigabitEthernet0/10 GigabitEthernet0/8

                    With this configuration the multicast traffic is limited to interface 0/8. There is no flooding.

For the second test :

               one Catalyst 2960 and two PCs

                             Group multicast= 234.56.78.90     ======> mac multicast = 0100.5e38.4e5a

                              Sender connected to port fast 0/10

                              Receiver connected to port fast 0/8

                              2960 configuration:

                                         default config +

                                        no ip igmp snooping

                                        mac address-table static 0100.5e38.4e5a vlan 1 interface GigabitEthernet0/10 GigabitEthernet0/8

                   Unfortunatly the traffic is flooded to all ports on vlan 1.

If someone can explain me if is there something i'm missing ....

Best regards,
