M4250 Multicast Troubles
Hey all,
I'm having toubles with multicast (I think) between a Cisco SG350 and a network of Netgear 4250 AVline switches. The netgear switches are setup in a star config with the Cisco joining the "core" netgear.
All seems to work however I'm having issues with a lighting node that requires multicast. The node is doing weird things so I am try to force send a specific multicast address to it. I believe everything should be configured properly. Some switches it seems to work but others not (configured the same I believe just a different number of ports). I'm using MAC filtering under traffic control for this.
The second issue I'm having (could be related) is I can't find how to completely disable the IGMP querier on the netgear switches for a specific VLAN. I am using the Cisco as the Querier but the netgears keep electing themselves even with election participte disabled on all.
Most of the networking I know is self taught so could easily be wrong. Any suggestions would be much appreciated.
Thanks

Netgear does have a wonderful feature named IGMP Plus on board of the Managed Switches like the M4250, M4300, M4350, and M4500.
Disable the IGMP snooping on the Cisco SG350, and let your Netgear core infrastructure do this job.
Technically, on IGMP Querier election process, the switch with the lowest IP address will win.
