Huawei MA5671A only negotiates at 1Gbps on Flint 4 SFP+ port

Router
1

Hello,

I just received my Flint 4 and I'm trying to configure it with my Huawei MA5671A ONU, which was working correctly with my previous router.

I'm experiencing an issue with the SFP+ port on the Flint 4:

  • Huawei MA5671A → connected to the 10G WAN port via a media converter: everything works correctly, and I can get around 1.5 Gbps over Wi-Fi (after setting uci set network.wan.vendorid=xxxxx)

  • Huawei MA5671A → connected to the Flint 4 SFP+ port directly: the connection works after setting uci set network.secondwan.vendorid-xxxxx

    but the link only negotiates at 1 Gbps, instead of 2.5 Gbps.

Is there a specific configuration needed for the SFP+ port to make the MA5671A negotiate at 2.5 Gbps?

Thank you!

Hi,

Thank you for the detailed information.

From the current results, the MA5671A can establish the connection successfully through the Flint 4 SFP+ port, but the SFP+ link is currently running at only 1 Gbps.
Could you please collect the following logs to help us investigate this issue?

  1. Please remove the MA5671A,wait one minute, then run:
dmesg -c > /dev/null
  1. Then insert the MA5671A, wait about one minute, export the output of:
dmesg
  1. After the one-minute wait, also run and share the output of:
swconfig dev switch0 show

Please also export the Router Log and send the logs to us via private message.
