[ Cloud Router Switch Series ] - packet loss in all devices

Hardware MikroTik hardware general
1

Hello, I have a question if anyone can check whether at home also have packet loss on devices such as: Cloud Router Switch
We noticed that the cable and the sfp have packet loss of 1% to 2%
The problem is only devices of this type, the other has no such problems, 0% losst.

tested on the desk.: network topology:
192.168.1.37 RB750U → LAN → 192.168.1.2 CRS125-24G-1S → FSP → 192.168.1.6 RB2011LS

test1
bandwidth test RB750 80/80M → RB2011LS


test2
bandwidth test CRS125-24G-1S 200/200M → RB2011LS


test3
bandwidth test RB2011LS 80/80M → RB570


test4
bandwidth test RB2011LS 200/200M → CRS125-24G-1S


test5


test6
192.168.1.37 RB750U → LAN → 192.168.1.6 RB2011LS FSP → 192.168.1.2 CRS125-24G-1S →

I was reading your post in trzepak.pl forum. In my opinion - bad configuration.
Primo - you have bridge, and ethernet ports in it
Secundo - you are not using switch chip.

All is working fine, if you know how to use it.

ping interval=0.02 size=1500 address=x.x.x.x do-not
Result:
sent=9743 received=9743 packet-loss=0% min-rtt=0ms avg-rtt=0ms max-rtt=0ms

Try this:
Set your ports to switch mode, delete bridge and use master port feture insteed.
than:
/ip firewall connection tracking set enabled=no
/ip fi man add action=set-priority chain=prerouting comment=“Prio DSCP na ICMP” new-priority=6 protocol=icmp

Can you show that you work with these devices correctly?
