PowerConnect 6224 PIM-SM

I'm already 2 days try to resolve a trivial task. Delivery multicast content from Summit X450a to PowerConnect 6224.

From the receiver vlan I see IGMP group:

#show ip igmp groups  interface vlan 303

IP Address..................................... 555.555.555.38
Subnet Mask.................................... 255.255.255.240
Interface Mode................................. Enabled
Querier Status................................. Querier
Multicast Group IP............................. 239.74.10.206

From the sender side not:

#show ip igmp groups  interface vlan 2606

IP Address..................................... 555.555.555.13
Subnet Mask.................................... 255.255.255.252
Interface Mode................................. Enabled
Querier Status................................. Querier

Also PIM servers on  6224 see anonces from summit:

#show ip pimsm rp mapping

Group Address.................................. 239.68.0.0
Group Mask..................................... 255.255.0.0
RP Address..................................... 555.555.555.129

Group Address.................................. 239.69.0.0
Group Mask..................................... 255.255.0.0

Group Address.................................. 239.74.0.0

Group Mask..................................... 255.255.0.0
