CSS326-24G-2S+RM really low performance speed

Hey!
I just bought a CSS326-24G-2S+RM, It has fresh RouterOS I didn’t configure anything yet just plugged it and I can’t get more than 25Mb/s

  • All ports are on the same bridge


  • Connected ether1 into my ISP router


  • I’m using Cat7


  • Low CPU%

I spent lot of time trying to configure it but nothing. I’m desesperate rn

You mean CRS ? CSS is a SWOS only device.

What is your testing method ?

That ether1 which is interface labeled mgmt/boot on the device sits on another switchchip (atheros) connected to the mgmt-cpu.

Your bridge (and you should only have one) will act on the marvell switchchip to which you must add all interfaces except for that mgmt/boot one.

Thats the case on CRS326-24S+2Q+RM and by the look of the blockdiagram it seems to be the same on CSS326-24G-2S+RM:

Edit: Uhm, nevermind. CSS326-24G-2S+RM only runs SWOS so things might be different there:

CSS326-24G-2S+RM seems to be a SWOS only device:

While CRS326-24S+2Q+RM can do both SWOS and RouterOS:

CSS is SWOS only device and CRS is i think dual boot.

@OP, @Apachez provided you with block diagram. If you have CRS device dont use MGMT port for nothing else.

If your ISP router dont have sfp then use RJ-01 i think, sfp to rj45.
