I try to configure a m4300 8x8f switch with three connected devices, a PTP source and two PTP receiver. But i have a problem, the switch seems to drop every ptp multicast packet. I have activated the general routing, routing on every interface, pim dense mode, igmp. In addition i can see the ptp multicast group on "routing/multicast/mroute table" with the right interface/ip source. Any advises will be welcome.
For further analysis, Could you please provide the tech-support file of the Switch: How do I send tech-support files from my Managed Switch to NETGEAR community moderators? http://kb.netgear.com/app/answers/detail/a_id/31439
According to your cli command display info, looks like port 1/0/11 and 1/0/13 didn't learn IGMP groups(224.0.1.129) member. One more question: Is the PTP receiver can generate IGMP report to join the groups(224.0.1.129)?
Could you please collect the IGMP packet statistics for port 1/0/11 and 1/0/13, the command as below:
But, I've a question, IGMP can works on Netgear equipments without IGMP snooping ?
Yes, my ptp receivers can generate IGMP reports, in direct connection everything works fine.
The results of:
........ 0

1. It's must enable global IGMP Snooping(but not necessary to enable on VLAN and port);
2. From the result of interface ip igmp status, looks like the port 1/0/11 and 1/0/12 didn't receive any IGMP report packet, the statistics is always 0.
(M4300-8X8F) (Config)#show ip igmp interface stats 1/0/11

Querier Querier IP Address............................. 192.168.2.2 Querier Up Time (hh:mm:ss) .................... 00:05:31 Querier Expiry Time (hh:mm:ss) ................ 00:00:00 Wrong Version Queries Received................. 0 Number of Joins Received....................... 0 Number of Groups............................... 0
The packets is received by the interface connected to the PTP emitter:
#show ip igmp interface stats 1/0/9
Querier Status................................. Querier Querier IP Address............................. 192.168.4.2 Querier Up Time (hh:mm:ss) .................... 00:46:02 Querier Expiry Time (hh:mm:ss) ................ 00:00:00 Wrong Version Queries Received................. 0 Number of Joins Received....................... 23 Number of Groups............................... 1
And, then dropped by the equipment.
Can you tell me which ip range is considered like multicast ip range for the switch ?
I've seen that netgear equipments have an option "Block Unknown Multicast Address", how can i disable it on m4300 8x8f ?
As I understand, the port 1/0/9 connect to PTP Source, the port 1/0/11 and 1/0/13 connect to PTP receiver, am I right?
If so, port 1/0/11 and 1/0/13 should learing IGMP groups from PTP reciever. And on IP mroute table: 1/0/9 should be 'incoming port', 1/0/11 and 1/0/13 should be 'Outgoing port'.
Beside: Switch with treat all RFC defined IP Range as multicast stream, 224.0.0.0—239.255.255.255
