Title: Mellanox Connect-X4 25Gbit/s not Working (working in pfsense)
Post by: wondaah on February 08, 2024, 08:08:55 pm

Hi,

I recently purchased a R86S-N305C which has two 25G interfaces from a MLX Connectx-4 card.

The issue that I'm facing is that it does not seem to negotioate correctly, I worked at my own ISP so I know what they have configured and I know it is correct.

Normally to get 25Gbit/s WAN Speeds we did set the Autoneg to off, Speed to 25Gbit/s and FEC to ON. I cannot see any documentations on how to do that except this thread with no answers on it.  https://forum.opnsense.org/index.php?topic=30467.msg146919#msg146919

Could anyone help me config wise to turn FEC on? Or maybe something more temporary than described in the above post?

Best regards
