I’d recommend not configuring the ssh interface unless you really want to connect to it right now.
The OpenWRT on there is horrendously insecure and ancient, so better not expose it in any way.
10G is wrong though, the module by default runs in 1G mode, and can be configured to 2.5G mode, but host support for that mode is uncertain, and setting that mode is immediate and irreversible.
If you are trying to access it like it’s a 10G SFP module, there’s your issue right there.
I remember reading somewhere that the OpenWRT build only supports 10G sfp module, but I don’t recall the reason or how to remedy it.
On normal Linux the module just worked out of the box, with the kernel auto-negotiating the speed and mode with it.
I have a spare SD card so i will try to build the Debian images and have a look if it works there.
Do you mind sharing what image you used or the build options?
The speed is read from eeprom, negotiation is turned off.
I also do not use openwrt, and I really don’t know, of all different version out there, which one suipports what. Hopefully eventually all is supported.
I’m running Gentoo on mine, so there is no image or anything I could provide.
But anything running Franks latest 6.9/6.10/6.11 kernels should just work.
