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,

Hello,
I realize that IGMP-Snooping is NOT enabled on 2960 - can you send me the results of "sh plat ip igmp snooping flood" ?
Do you have any SVI up and running for that Vlan ?

Hi Yogesh
Please find here the show platform ip igmp snooping flood command.
We are interested by vlan 100
TU-DMZ-01#sh platform ip igmp snooping flood
vlan l2rcnt local hl3mm system
---- ------ ----- ----- ------
1 0 enabled disabled

102 0 enabled disabled

For the last question, there is no SVI up or running for the vlan 100.
