Vyos on Problem of Network

My Updated Fiber7-X VyOS 1.5 Config

Wed, 12 Jun 2024 13:00:00 +0200

A while ago I wrote about my VyOS config for Init7’s Fiber7-X product. Since then there has been a number of breaking changes, and a few additions that I would like to cover.

I will copy/paste a lot of the narrative from that post, and avoid a bit of the abstract conversation that went with it, so that this stands on its own.

If you have questions or comments, hit me up.

10G Router7 Install

Last year I wrote extensively about my experience with deploying VyOS to support my new uber fast internet connection.

I learned a lot in the process, and for this past year it has mostly worked fine. I am one of those people that can’t leave things alone however, and I was always tinkering with the setup. The VyOS box itself was happily communicating at 10G, but I would find the internal LAN would get choked up a lot and rarely hit 1G even with extreme threading (say 50-60 conns). I got grumpy about this for no reason and started to tinker. TL:DR - This was a mistake…

node_exporter in VyOS 1.4

So it turns out that if you want metrics from VyOS, your two options are SNMP or Telegraf (towards InfluxDB).

SNMP is one of those things that has been around so long, you think its good, but really, its trash. Its a 1990s technology that is mostly singlethreaded and provides you very very fuzzy numbers. 5 min averages are not that useful in situations like today where clients plausibly have access to gigabit+ grades of connectivity. If you cant observe let alone react to a microburst, you’re pretty much blindfolded in a modern DC network setting.

My Fiber7-X VyOS Config

Updated Jun 2024: This Vyos 1.4 config is now broken if you use a recent vyos 1.5 rolling release. I made a new post here that mirrors this one, but with the correct syntax!

Updated Aug 2022: After moving house I have been able to split my install between the basement and the house, so I bought myself an Dell Optiplex 7050 to be the VyOS router (the OTO is in the house), and then run a 10G fibre to the basement for the rest of the stuff. I think I will leave the post as is because the VM method is more interesting, but I will add a block on that below.
