Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+

CRS317 replaced with UBNT EdgeSwitch 16XG. Problem solved. I will not wait for the device to stop 1Gbit traffic.

I won't wait for it to ever be fixed. Similar to flapping on RB3011 and the like.

Re: MUM Europe 2019: new hardware

It's just a USB device just like an ethernet to a USB or wifi dongel. It has no CPU in normal words meaning.

But the sense of this device escapes me.

You write that 8 CRS317 are waiting for repair and then they do not have the problem. I do not understand.

  I also have CRS317 and CRS328, and sometimes I do not have management on both the two and the data impediment.

Next time I prefer to buy something from UBNT where there is no problem.

Re: CRS328-24P-4S+RM speed problem

nice, but the problem arises even when the 800Mbit queue is used on the uplink router to crs where the buffers in the CRS should work at rest so it does not work anyway. It still can not reach even 800Mbit. Similarly, it can be converted to 1G to 100M ports. This normally handles other devices. CRS ...
