Re: CRS312-4C+8XG-RM questions

CRS312-4C+8XG has Marvell-98DX8212 switch chip and supports the same features as CRS317-1G-16S+ including 10218 byte Jumbo Frames.

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

Our investigation has revealed that there might be a SFP+ compatibility issue with specific CRS317-1G-16S+ units when connected to other CRS3xx devices resulting in random link downs. Please, contact MikroTik support if you experience similar issue, we will verify it and arrange a repair if necessary.

Re: CRS317-1G-16S+ FAN, SPF and RSTP problems

SwOS v2.9 has few changes which require updated fan controller firmware that comes only within RouterOS.
Please upgrade the CRS3xx to RouterOS v6.44beta61, the fan firmware will upgrade along with it.
Then you will be able to use SwOS v2.9 and can downgrade RouterOS if necessary as well.

Re: SwOS version 2.9 released!

Upgrading from 2.8 to 2.9 on a CSS106-5G-1S causes severe traffic drop between 1G ports and 100Mbit ports. It's random from 0 to 40Mbps.
Reverting back to 2.8 traffic increased back to steady 100Mbps.
Are there any errors in interface stats when using v2.8 or v2.9?
