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,
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.

Thanks, file and link sent as requested
Just a thought, while I appreciate the community and tech support, it's worth mentioning that this policy of requiring Netgear branded SFP+ does prevent some of us from purchasing more of your switches...
As an example, the current Amazon price for the SFP+ mentioned is $313.50

An SFP+ that's comparable for your competitors switches (Cisco and compatible) is $19.99

It's great to see the quick response from a Senior Product Line Manager here on a community support board, and it helps to know Netgear is listening to the issues we experience. It would be great to see Netgear test and validate some less expensive modules for use in these switches. Many of us in the industry have a drawer full of "compatible" SFP+ that just work in almost all of our other gear.
Thank you for your thoughts, this is good feedback! Yes, third-party modules can seem cost effective, when there's no interop issue. All major networking vendors experience same dilemna, how to offer high quality solutions with strict, intensive QA testing for perfect interop with genuine modules, and how at best support variable quality modules in the field. Should that make a difference for you, we also offer packs of 10s for our NETGEAR genuine 10GBASE-SR and 10GBASE-LR transceivers with better pricing incentive: for instance AXM761P10-10000S.
Back to your issue, our teams are on it. You might be contacted by PM or email from now on, and the Community will continue to monitor this post.
