IP addresses of the devices should be on bridge interface and not slave interface ether2. What does Tools-->Profile show when you do transfers through the devices? Sorry for my late reply. I changed the IPs to bridge interface and if i check the tools-->profile, the CPU seems to be normal when I ru...

Thank you both for your inputs. Are you certain the fiber terminations are clean and free of any defects? Only time I've seen bandwidth that poor on even a 1G SFP was dirty fiber. Fiber should be fine, since I've tested it with various cables and with different modules. Also I tested it on all 4 Por...

Hi all, I have a question related to the bandwidth-test tool within RouterOS. I am operating in a test-setup 2 CRS328-24P-4S, and they are connected directly via a SFP+-Fiber Connection. When I do the Bandwidth-Test within ROS, I get very disappointing results: Protocol Port Connection Port TX/RX (M...

Since I am dealing with a similar set-up / problem I am quite interested in the progress. Did disabling the IGMP snooping improve something? Additionally, did you do a Bandwidth-Test (via Winbox) between your switches? I have 2 CRS connected via Fiber, but only get ~400 Mbps on UDP (&also loose ...

Great, thanks for the confirmation. So basically, for the "blue" network I should be able to assume a rough max. throughput rate of 48Gbps (non-blocking Layer 2 throughput @ 64byte) for switching between the 2 switches. (Going back to my initially mentioned example, handling 33 clients wit...

Hi @mkx, thank you for your feedback & explanation. Just to make sure I understood you correct as well as applied to my use-case: - Switching: Moving Ethernet Frames from one Interface to another, within the same IP subnet. - Bridging: N/A in my case (no VLANs needed / active) - Routing: IP pack...

Hi all, I am a bit confused & lacking probably the knowledge when reading the Test-Results page for the CRS328-24P-4S+RM. https://mikrotik.com/product/crs328_24p_4s_rm#fndtn-testresults Is there somewhere a Guide/FAQ/WIKI where it is explained, what the differences are between Switching / Bridgi...

Hi -
how are the Switches connected to each other, are the red cables in your sketch Fiber or Copper?
I had/have similar performance problems when using fiber ports on the CRS - just for testing using the LAN ports & Copper might be worth to try...

Try downgrading to 6.44.5 long term version, suggest using netinstall to do downgrade Thanks for the suggestion CZFan, I downgraded and 6.44.5 is running now - unfortunately still the same performance. The weird part is that the download (~0.36 Mbps) is way slower than the Upload (93 Mbps) - for me...

Hi all, I have a speed issue with my CRS328-24p-4s+rm, when connected via SFP+ ports. I have a server connected via SFP+ Fiber cable (10Gbps) to the crs328-24p-4s+rm and a direct copper link to the ISP Router (1Gbps). I realized some internal speed problems and if I do a basic Internet speed test, t...

Dear all, I have some questions related to a desired set-up and some issues which don't work - any input/feedback is appreciated, thanks! Set-up: Router "0" (ISP) --> Router #1 running RouterOS (CRS328) --> Router #2(CRS328) running RouterOS Router 0 to #1: RJ45 to ETH1 R#1 to R#2: Fiber v...

Hi all, I recently bought a CRS328-24P-4S+RM Router and would like to set-up a separate network behind my ISP-Router. I am kind of new to networking but I thought i could make it work with my computer knowledge and Internet research - unfortunately not yet :? This is the idea/current set-up (picture...

Hi all, just to jump as well on this post - i have the same issue (with another Router/Switch though) but same problem: WinBox can't find the Switch and also no Browser can log in (192.168.88.1 nor .2) I was logged in initially into the switch via WinBox and MAC-Address (RouterOS) but changed the bo...
