M7300/M4300, and all netgear managed switches, apparently do not support LACP fallback mode
We have both M4300 and M7300 10GbE switches from Netgear in our environment. It does not appear that any netgear switches support LACP fallback mode. We already checked with support and tried the latest firmware. In other words, LACP is either enabled or disabled. There is no way to have it enabled, but to automatically fall back to disabled, when appropriate.
This creates significant issues in our environment, and for many others, as any kind of re-imaging of a server using PXE will fail. There is no way to have PXE enable LACP, so as soon as the server reboots and goes into PXE, we lose connectivity. Even outside of PXE, if you take a typical ESXi server that has LACP turned on and then try to reinstall ESXi off a ISO image, you cannot configure LACP during the install, so the 10GbE ports will have no connectivity.
Cisco, Arista and every other switch vendor we have seen has some kind of setting to turn on LACP fallback mode. On catalyst it is turned on by default. On nexus it is enabled with "lacp suspend-individual", etc., etc.
It would be great to get some feedback from Netgear product management on this topic, as this greatly limits how we can adopt this switch in enterprise deployments.
Thanks,
FYI, I am waiting for a response before I post this on other forums and product reviews to make sure this is not a mistake or some kind of hidden feature that I could not find.
Hi ecsrun27
Thanks for your post, your contribution to the Community is instrumental. I've made some research and you are correct, we do not have option to fall back and disable LACP automatically when LAG is down due to the absence of LACP. I agree that it would help in cases like this. We need to prioritize such equivalent command to lacp-suspend in our Fully Managed Switch software roadmap. Let us work on this. We can't deliver any ETA at this point, but your voice was heard. Please don't hesitate to reach out to me,
Regards,

It is great to hear that the Netgear team is listening to the customer base! Thanks for your response. We understand that this won't happen overnight, but definetly looking forward to when this feature makes it into the product.
Cheers,
Thank you for helping us deliver better products. I will come back to this thread as soon as we have made some progress towards it in our software. Your use case makes lot of sense, thank you again.
