CRS112-8G-4S > No 100mbps fiber

Fri Aug 30, 2019 11:06 pm

Hi All.

Hope you can help. I had this device for almost 3 years.

I understand it is not a Router, But at that time I received it as a gift. CRS112-8G-4S

I always had ADSL 12mbps and now My work installed me 100mbps Fiber. I reconfigure the unit and I only get 22mbps (Speedtest) out of the unit. I have read up on old post (2016), I find the problem that it is the CPU that can't handle the workload as it is configured with Bridging mode. so I read up that I need to change it to master ports and slave ports.

My problem is that with all the new software upgrades the step is not the same. Can someone help me? I really want to use the full speed of my fiber connection fiber.
I have added a picture of the speed test and the load.

Here is the config of my router, I reset it as I thought there is a setting causing the slow speed.

I will really be very happy if someone can help me!

I don't think the problem is in switching v.s. bridging, this distinction only affects ether interfaces that are handling traffic for same broadcast domain, in your caee the Skynet subnet. Your current setup probably offloads traffic to switch chip as it is, you can verify it by executing command /interface bridge port print ... if all ether ports show flag 'H' in front of interface names, then you're good.

I guess the big problem in your case is routing and firewalling between ether1 and Skynet ... do you have firewall configured at all? It's not in what you presented, but I believe that the problem lurks in that bush.

Official test results for your CRS do show, that simple routing without filter rules can be quite slow if packet size is small (PPS gets limited). With full-size packets your device should be able to route at leas few times more than whst you get. And who knows what test app used actually does ...

Just one more test: run profile on CPU and observe which processes consume most of CPU while you're running throughput test ...

This is a Switch and not an Router, your CPU is not powerfull enough for this what you Are doing you could try Fasttrack but in my opinion, you better buy something with more Power

Hi understand.

Fast track is on! I can't afford to buy some new.

What until will worth saving for? More then 8 ports / rack mount and have an lots of power two. Need to connect vpn as well do lots of firewall rules

Keep using CRS as switch and go for something small as router .... RB750Gr3 would do fine. Or a RBD52G, you'd get wireless for free. Both have HW acceleration for (some variants of) IPsec encryption ...

You claim that fast track is on, yet in your config there is nothing under /ip firewall filter.
If that isn't a deliberate omission on your part, use this link to properly enable fasttrack:
https://wiki.mikrotik.com/wiki/Manual:IP/Fasttrack
Also note that FastTRACK and FastPATH are not the same thing.
After that, you should also look up some default firewall rules and secure that router a bit.

As always, use Safe Mode :wink:
