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.Solved4KViews0likes11Comments
Trunking between 2 switch stacks (M4300-52G-PoE+ stack & M5300-52G-PoE+ stack)
I'm not a networking expert, so I wanted to toss this question out there to see if someone could point me in the right direction. I have (2) seperate network stacks in 2 seperate builtings connected by a SFP+ fiber trunk connection on ports 1/0/51 on both stacks. I'd like to connect a second SFP+ fiber/trunk connection between both stacks on port 3/0/51 to increase redundancy, but Im not sure exactly how to do it without creating a LOOP situation. I've never done any kind of LAG configuration, but everything I read tends to point me in that direction. I found a post discussing how to configure a LAG ( https://community.netgear.com/t5/Managed-Switches/sfp-trunking/m-p/1061504# )and the person posting referensed a document titled how_to_configure_lag.pdf, but that seemed to confuse me even more, since the browser GUI in that document looks nothing like the browser GUI on my M4300 and M5300. The article also mentioned needing to configure STP on each stack to prevent a LOOP, but I cant seem to find any documentation that can better educate me on how to do this. If anyone out there has any links or insight they can provide me when it comes to combining 2 SFP+ ports into a LAG and then trunking to another switch that also has 2 SFP+ ports combined into a LAG it would be greatly appreciated.
