Hello all, let me apologize in advance if this has been brought up, but I did not find anything specific enough to get my new system up and running correctly. I am used to Cisco iOS hardware, and this is my first shot at Mikrotik hardware. I am trying to downsize and consolidate my home network hardware to using just the CRS125-24G-1S-RM. I am using a modified out of box config on the device (Upgraded Firmware and RouterOS to the latest, put in switch mode, setup DHCP, WAN to Eth1, upnp enabled). My issue is that I am incurring several dropped packets, and cannot get over 500 megabit connection utilizing the bandwidth test, and that pins the CPU to 100%. I am also not getting over 35mbs on any hardwired devices to WAN. Using my old setup, i was achieving 940mbs+ but that is utilizing a lot of power, 3 different pieces of hardware (Router, Switch, Wireless Access Controller).

Any input would be appreciated.

"CRS125-24G-1S-RM" is powerful switch but simple router

Hi,

CRS125 has rather weak CPU so it may not handle all the things you want to do. Saying that I'm using CRS125 as my home switch/ router. I have 70Mbps up and 10Mbps Internet connection, whole bunch of firewall rules and for most of the time CPU usage is around 5%. Use switch chip where you can instead software bridges. Anything done in software will hammer the CPU.
Use fastpath if you can on your WAN links and be smart when you create firewall rules. I would not go as far as using QoS and packets marking on this device.

Here are few links, which can help you:
