m4300-28G-PoE+ High CPU Utilization
Hello there.
Using a m4300-28G-PoE+ switch for Dante audio, as well as multicast Video over IP.
I'm seeing VERY high cpu usage, (averaging around 84%), and 50% or more of that is coming from "snooptask". Should I be worried? What happens if it spikes to 100%? What should I be looking for to troubleshoot this issue?
Thanks!

Welcome to Community!
Don't worry, "snooptask" is the component to handle IGMP Snooping traffic, as your switch is using for Dante audio, as well as multicast Video over IP. There is a lot of mulcast that switch need to handle, so it's a normal case.

- So no worries about the high CPU usage otherwise? Is 89%+ normal?
We experienced the same on our stack of M4300 switches. snoopTask was consuming all the CPU.
To date we found firmware 12.0.4.7 has been the most reliable but every 30 days the CPU usage creeps up and we have to reboot the stack in oder to keep IGMP/Multicast working properly.
We've just upgraded to 12.0.7.17 and are having issues again.
I have cases open with support to diagnose the issues.
Glad to hear I'm not the only one with issues. A switch sitting at 80%+ CPU seems really suspicious to me. Mine doesn't creep up however, it jumps right to 80%+ after reset.
What is odd is I have another site with M4300 switches (stack of three, one M4300-96X and two M4300-28G) with WAY more going on, and only 40% CPU utilization.
Let me know how things work out with support.
Ok, 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?Regards,
