It's just the normal rc.conf lines with `ifconfig_cxl0=3D"inet =E2=80=A6"` = and `ifconfig_cxl0_ipv6=3D"inet6 =E2=80=A6"`, nothing special beyond that. > Provide the output of these commands when the link isn't up: > # ifconfig -mvvv <interface> > # sysctl -n dev.t5nex.0.misc.devlog Thanks, I'll try these when I'm back at work tomorrow and report back. > > send and receive light as they should.

Does that work? ifconfig down/up did not help, I tried that first (I should have mentioned = it in the original email). Figuring out it would work by physically removin= g and reinserting the SFP was a side effect of initially trying to figure o= ut if this was a hardware issue. --=20 Marius Halden
