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

It's very normal to have issues on copper port, because of potential difference generated by two sides of the cable. On twisted pair technology this must be no problem at all, but very often it is indeed. On the other hand optic ports have no such problem at all and power related problems are just f...

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: Problem ICMP/TRACEROUTE CRS317-1G-16S+ [SOLVED]

There are lot known bugs on SwOS 2.8 and 2.9, especially for CRS317, and we waiting more than 8 months MikroTik fo fix it.... Keep your switch to SwOS 2.7 to avoid problems.
Check there is a lot of topics about this.

  • use CRS317 with SwOS (no other ver than 3.7) instead of RouterOS

Not well done MikroTik - hardware related problem?
And why when you switch to SwOS there is no such problem, only CRS3017 with RouterOS?
Same hardware - different behavior = simply software bug!

Hello, SwitchOS is one big pile of shit with no real featues, as it was intended for the general audience. When i add SFP media converters or non-mikrotik or unmanaged switches on the other end it does not pick the link up. But ROS does, hence we cannot use SWOS at all (As a last resort even if it ...

Same here!
Lot of tx/rx overruns on 10G port (SFP+ to CRS317) or pauses when flow control is enabled.
I'll wait till next SWoS release and if it is not fixed will throw away and will declare it as another cheap junk.
