right, but those are copper interfaces. > I am using transceiver modules AXS85-192-M3 from 10Gtek. It looks like they are not flashable (like flexoptix and others), so I presume these are "non-Intel"-branded. > The allow_unsupported_sfp=1 does not make a difference. Shouldn't there > be at least a syslog message if an unsupported sfp is detected? Just to be extra sure, you've added: ixgbe.allow_unsupported_sfp=1 to your kernel cmdline, right? I've checked with an up2date bookworm test-server and kernel 6.1.12-1.. when inserting a Intel-branded flexoptix SFP, I'll get this message: Feb 27 14:59:06 xxx kernel: ixgbe 0000:5e:00.0 ens2f0: detected SFP+: 5 whereas with a Arista-branded one, I'll get the same: Feb 27 15:00:30 xxx kernel: ixgbe 0000:5e:00.0 ens2f0: detected SFP+: 5 Just to document it.. this is dmesg from after rebooting the machine, there's no allow_unsupported_sfp set at all, and there's an Intel-branded SFP in one slot (ens2f0), an Arista-branded one in the other (ens2f1): [ 3.178235] ixgbe: Intel(R) 10 Gigabit PCI Express Network Driver [ 3.178385] ixgbe: Copyright (c) 1999-2016 Intel Corporation.

Hope that helps - my guess would be to try and verify with an Intel or Intel-flashed SFP to rule out. Hope that helps. Regards, Daniel
