Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+
Hi! I just found this topic. Did you use the Mikrotik switch through an UPS(uninterruptible power supply - sinus wave type) hardware ? If not, then this maybe a main problem - the power supply might have receiving some OVP/OCP/SCP effects - causing the port flapping. In my case - yes, they were on ...

Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+
If the problem is on power supply there will be port flapping always, no matter what OS is running. I have always port flapping when winning RouterOS (every single version on it) and never when running SwOS 2.7. We have a lot of 317 some connected to 326, 328 - different versions, all with SFP+ 10G...

Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+
Hi!
I just found this topic.
Did you use the Mikrotik switch through an UPS(uninterruptible power supply - pure sinus-wave type) hardware ?
If not, then this maybe a main problem - the power supply might have receiving some OVP/UVP/NOISE effects - causing the port flapping.

Re: CRS326-24S+2Q+RM Question
Hi!
The "CRS326-24S+2Q+RM" is an L2 switch.
Do not consider as an L3 routing core - CPU resurces is not enough - you will end up serious lags/packet drops.

Re: I cant get more than 50 Mbps through a PtP Netmetal 5 link
Hi, yes, it´s real... why I will false this test? 1434Mbps / 8 bits = About 180 MBytes, tomorrow will test with a Gigabit ethernet port computer and try to make a test with iperf... today make a iperf test but two sides PCs are connected through a wifi router and max speed are 3 Mbytes. The real te...
