M4300-12X12F 24-Port Managed Switch 10G link fails to come up with Intel SFP PN: FTLX8571D3BCVIT1
When Intel SFP PN: FTLX8571D3BCVIT is used inside M4300-12X12F 24-Port Managed Switch the 10G link fails to come up, an only way to get this link up is to go into switch configuration and make a manu...
Hi Demi-California
Welcome to the Community!
Can you explain the manual update to settings you are forced to make on M4300-12X12F in order to see the link established with FTLX8571D3BCVIT1? As you can read here, these SFP+ transceivers are advertized by Intel® as "compatible" with X520 NICs, but not with certain other NICs. To me this is not a good sign first thing, I am wondering which interop one would expect with a 10G switch?
To answer your question, we strive to offer maximum compatibility with standard based, high quality third-party modules, but we don't claim universal support. Our M4300 documentation specifies NETGEAR-only compatible modules. There are thousands of modules on the market, and NETGEAR designs and tests its switch products for use with genuine NETGEAR Modules only. The use of third-party modules may result in reduced network performance and reliability, such as packet loss and connectivity issues. While the use of third-party Modules does not affect the NETGEAR switch's warranty, NETGEAR may not provide technical support for networking problems it determines are caused by third-party Modules only.
The Community is going to help you, before we open a case at Technical Support. Learning which settings you have to change on the switch will be a first step.
Next, it will be useful to learn what is located at the other end of your fiber connection: is it a server equipped with X520 NIC and that FTLX8571D3BCVIT1 transceiver too? If yes, did you try another combination, for instance the FTLX8571D3BCVIT1 transceiver in M4300-12X12F and another transceiver on the other end? We need to nail down the issue as much as we can here. Often server connectivity issues with a 10G switch come from outdated driver for the NIC in the server for instance.
Please let us know!

Hi Demi-California,
1) when you said it failed to come up with 10G, did you mean the link is down or the link is up, but at 1G?
2) Could you provide the techsupport file? you can upload it to PC through GUI: Maintanence->export->http file export, select the 'techsupport file' in the drop menu.
3) what's the partner device? is it another M4300?
I see the same behavior on an M4300-28G and using Intel SFP+ modules. They work fine with autonegotiation and at 1Gbps, but to get a 10Gbps link I have to manually configure both ends (NIC is an Intel x520).
The problem with this fix is that the configuration appears to be lost after each reboot or power cycle of the switch. That means the link won't come up, despite the switch seeing the SFP+ Ok in the tranceiver menu. To fix this, all I have to do is select the port in the Switching->Ports->Port Config screen and then click Apply. Somehow this wakes up the port and everything works again at 10G.
Any way to get these SFPs to work and keep their 10G link config thru a reboot?
Running 12.0.2.9 on an M4300-28G, using either Intel FTLX8571D3BCV-IT optics or AFBR-703SDZ-IN2 optics (same behavior on both), and Intel x520 NICs
Hi Zebibyte
I understand you're using Intel SFP+ modules in your Intel x520 NICs. I think you are doing so because Intel NICs might not work with third-party SFP+ modules. In our M4300 documentation, we specify NETGEAR-only modules. Why? Because NETGEAR designs and tests its switch products for use with genuine NETGEAR Modules only. The use of third-party modules may result in reduced network performance and reliability, such as packet loss and connectivity issues. While the use of third-party Modules does not affect the NETGEAR switch's warranty, NETGEAR may not provide technical support for networking problems it determines are caused by third-party Modules only. In your situation, best would be the Intel x520 NIC equipped with this Intel SFP+ module --> multimode fiber --> NETGEAR AXM761 10GBASE-SR SFP+ module in M4300 switch.
To answer your question, we strive to offer maximum compatibility with standard based, high quality third-party modules, when it's possible. We don't claim universal support. The Community is going to help you, before we open a case at Technical Support.
First, please log in to the command line interface of the switch, and from enable mode, run the command: show tech-support. When done, you can proceed with the Web GUI. Please log in to the web interface, go Maintenance->Export->HTTP file export, select the 'techsupport file' in the drop menu.
Please send us the Tech Support file by email to switch_support@netgear.com. Please don't forget to include a link to this post on the Community forum. With the Tech Support file, we will be equipped to understand the problem with these SFP+ modules.
