RB5009 2.5Gbe not working?

RouterOS General
1

Hello,

I got 10Gbps internet from my ISP previous week and I’m having trouble getting more than 1Gbps from them. I updated to the newest ROS version: 7.11.2. Do you need to enable something to get more than 1Gbps on the 5009 Series or am I doing something wrong? Profiler shows CPU utilization ~50-30% on all cores when getting 800Mbps.

I’m currently running the most basic config:

You need to enable fasttrack (Google/MT wiki)

The RB5009 CPU should easily be able to handle more than 800mbps though. What’s on the other end of the link? Numerous 2.5 GbE cards require firmware updates or similar to function properly, the popular Intel i225/i226 line is pretty much broken for example.

Hello,

thank you for the reply. On the other end of the link is my PC which has an integrated NIC on the motherboard(Realtek Gaming 2.5GbE Family Controller). Just changed the UTP cable from port 1 to my PC and still getting ~800Mbps instead of more.
I also tried using fasttrack but it doesn’t do anything other than lower the cpu usage. Still stuck at 800Mbps.

You could try this:
Go to System->RouterBOARD->Settings->CPU Frequency and change it from “auto” to “1400MHz”.

The auto scheduler is limiting the performance a lot. Maybe this improves your situation.

I have cpu set at auto, no problem getting 2.5gb on vlan trunk between rb5009 and ax3.
