Switch drop PTP multicast
Hi ,
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.
Best regards
Problem fixed, IGMP on master clock was is in version 2 but IGMP on netgear switch was is in version 3. Downgrade to version 2 and all works fine.

Hi KrustyK
Welcome to the community!
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?

Hope it helps!

Hi KrustyK,
Got the tech-support file from you. Thanks again!
Looks like the configuration is correct!
Could you please run CLI command on the switch as below:
1. show ip mroute summary
2. show ip igmp groups x/x/x(the PTP receiver port number)
3. show interface counters(do 'clear counters all' first)
BTW: I try on local switch, it's success. DUT can forward the multicast packet success.

I have try:
set igmp
set igmp header-validation
set igmp querier
set igmp proxy-querier
But PTP multicast traffic is still dropped.
So, this is the results of the commands:
1. show ip mroute summary
Multicast route table summary
