Hello, A number of people have been suggesting Lanner boxes for routing. I have used FW-7543A and FW-7573A boxes with Debian with no issues. I am currently trying the NCA-5510 model with NCS2-IGM806B (XL710) and NCS2-IXM407A (I350) cards with a standard Debian Stretch installation. I was hoping that it would be as easy as installing the operating system, turning ports up, and getting a working network. It was like that with the other models. Not with this model. There seems to be a bunch of different BIOS combinations which give different (bad) results. And for the combinations I've tried, I can't seem to get the XL710 card to work properly. Maybe I should have gone with the 82599 card instead. In addition, the I210 based management port also isn't coming up properly, always some sort 'interface reset' error. Which, with some bios settings, I get on the I350 cards as well. If someone has a similar model and/or configuration, what sort of BIOS/Kernel settings have you used to get something operationally stable? Any particular Kernel versions work best? I tried 4.9.51, and 4.14.3. It seems to take about 48 hours to get turn arounds from Taiwan engineering, which I am currently trying to escalate from a sales office, but was hoping, in the meantime, someone else might have some experiences to share? I can provide console / kernel messages to show what I am encountering for those interested. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
