CRS354-48P-4S+2Q+ port drops?

Hi,

Recently got this switch as part of my network. Installed it (latest firmware both packages and routerboard) and noticed that it "crashes" after a couple of hours, certain devices drop from the network. At first, I thought it was the DHCP lease from my 4011 router but apparently it's intermittent on the switch for sure since the LAN devices go offline (“network cable disconnected” message). For example, Various PoE CCTV drops from the network (so not always the same CCTV), once it even knocked out the NVR from the network. I always have to reboot the CRS to get it back to working normal. Anybody else experiencing this?

I'm currently using the RouterOS for switching (no routing at all). I've reset the CRS. Removed default settings. Bridge getting IP from DHCP. Still sticky. Was not having this issue when using a dumb generic switch. I like being able to control the unit using Winbox. Would it be more stable to just use SwitchOS for my usage?

Any suggestion is appreciated

All CRS354 have issues. It is not known if there is a problem between the hardware and ROS or its a hardware issue.

Its an old issue, but mikrotik doesnt care about it. A switch that doesnt forward traffic, this is amazing.

At this point, replacing with other vendor is the only solution.
