Glad it worked out for you... I ended up grabbing a Mikrotik CRS305 and one of their S+RJ10 SFP+ to RJ45 modules as I couldn't find a supplier that had stock and/or would ship to Canada. I'm still shopping for one of the Supermicro modules but I suspect I have another issue to fix - specifically the onboard 5Gbps NIC itself. The Mikrotik is really revealing the issues with the onboard 5Gbps NIC (Aquantia AQC111C) on my Asus Prime x299 Deluxe II. Specifically the random disconnects... when it happens I have to either unplug/re-attach the cable or reboot the Mikrotik. Thankfully under SwOS it takes less than 20 secs to reboot, but it's still a major annoyance.Just confirm that I bought a Supermicro Aquantia AQS-107-B0C2-CX 10G on ebay for $125 , and it's working great at 2.5Gbps from my main PC with a ASUS TUF X570-Pro motherboard, so far iPerf got 2.2 and 2.3 Gbps sustained,
since that was the last one from that vendor, now in the hunt for another one at a reasonable price
Thanks again for the reply
I have a case open with Asus regarding a firmware updater for the NIC. The official updater from Marvell (who bought Aquantia) doesn't work on my motherboard, and neither does the community modded version which has added IDs for some Asus motherboards. Asus themselves state there's no known problem with the NIC and no firmware updater is available - they want me to RMA the board. But a simple Google search shows many with similar issues to what I'm experiencing, and most are resolved by updating the NIC firmware. And many of the posts about the issues are in Asus's own ROG forums. They've used the Aquantia AQC111C on a number of their products in the regular and ROG lines.
I provided a bunch of these links to Asus and am waiting to hear back. If I could figure out how to find the required ID info for my board, I'd add it myself to the XML config file in the updater. That XML file contains the IDs of systems that the updater works for. Hopefully I can get mine updated and it resolves my issues.
In the meantime, I have a LOT of learning to do about configuring my home network. I'm having difficulties with VLAN and/or port isolation but I'm sure it's just a lack of knowledge issue. Back to my reading...
