Re: Multicast across switches does not work (CRS3xx)

Like "futurion" I have reported many times that IGMP/multicast does not work properly. Mikrotik lies that it works in SwOS and does nothing to fix it. It is a waste of time to use Mikrotik if you want to use IGMP/multicast. I test every few months and nothing changes. Mikrotik produces a l...

You can't do anything with X710 this card doesn't work well with mikrotik. I've been testing for a few months. Intel E810 is great.

Re: After rebooting RouterOS x86 7.15.3, the link on the SFP+ port of the Intel X710 disappears

Intel X710 is a very bad card with problems, please don't even try to use it. I recommend it, it works perfectly in Mikrotik Intel E810, the system is newer, faster and has more functions, for example: Intel E810-XXVDA2 Ethernet 10/25Gb 2-port Compatible SFP-RJ45, SFP, SFP+ and SFP28 Adapter Intel E...

In OS 7.18.0 mikrotik increased the number of entries from 1048576 to as many as you have RAM 1GB = 1028096 example 8GB = 8224768 entries. As many entries as you have memory.

Re: After rebooting RouterOS x86 7.15.3, the link on the SFP+ port of the Intel X710 disappears

Hello,
Mikrotik has broken something in the drivers and currently all cards with the Intel Ethernet Controller X710 chipset have stopped working.

Report the problem to Mikrotik support and maybe they will fix it faster.
Don't waste your time, it's a driver problem.
