Hello,

I got an CRS354-48G-4S+2Q+RM for 1 year now and i have some problems with it, i never test it when i buyet, just plug and go.

My network is like this

1GB x 4 ISP > 1GB Port > From Router (10GB Port) > Switch CRS354-48G-4S+2Q+RM (40GB Port) > Server With 10GB Port Or From the 1GB Port to 1GB Port Server

If i move files betwin servers with 1GB to 1GB Ports or 10GB to 10GB Ports or even mixed the speed is not stable it starts with 100MB (1GBport) but after a couple of secands it drops to 15-20 and a couple of secands go back to 100MB and it keeps making like this, dose not metter if is 10GB to 10GB or 1GB to 1GB or Mixed.

So i was thinking there is sompting wrong with the servers, they ar all E5-2690 v3/v4 with Enterprise SSD, they have like 2 years the servers.

I took an Cisco 4948 and change it with CRS354-48G-4S+2Q+RM to make same test , and it keeps speed to 100MB and not dropping til he finish.

Dose anyone got any ideeas if there is some sort of issue with this CRS354-48G-4S+2Q+RM ? Or is there sompting i have to setup on it ?

The test i made is with wget, from a server to another to check where is the issue because we have 4 GB lines from ISP and the bandwitch is Guarantee
If i wget a file from another location, datacenter...etc it go with 1GB Speed and not dropping, test made on Cisco, on the CRS354-48G-4S+2Q+RM it makes same problem like i metioned.

I have RouterOS v6.48 (stable) on it when i buyet whanted to change to SwitchOS because i use it as switch and it dies when i change it, i read here there is some sort of issue with this, i dont know if they fixed or not.

Thank you

Good Morning,

Can you please export your Config and Post it on the Forum (/export hide-sensitive file=anynameyouwish)

Hello,

I didnt configure nothink on it just left default the way it comes

Guten Morgen,

I don't have a CRS354 in my LAB, so i can't do any Test...
I know some Mikrotik-Devices have performance Problems, as soon as a 10/100 Device is connected

For diagnostic purposes,
you could try to disable Interface "D12 - Port 17", reboot your Switch and do the Test again.

Dont get it what dose this has to do with the port "D12 - Port 17"

Even if o do the same think from D9 to D8 or D8 to D9 it makes the same.

I even rebooted the switch, still the same

I just got the same switch and copies just fine, but i installed V7 on it immediately as i got it, so cant hurt to try also its running perfectly stable(for now).

In the Config the Interface "D12 - Port 17" negotiated 100mbits with the Client.
Some Mikrotik-Devices have a performance Problems on the Switch, as soon as a 100mbits-Device is connected.

Its strange, i didnt limit any ports at all.

I will change the server port and after disable the port and make some test.

Do you use RouterOS or SwitchOS ?
