Sep 15, 2020 · do you have trouble with port flopping? Here is "answer" from support.This "trouble" is writen nowhere in specification. RB3011 is CRAP and Mikrotik makes bad device. The reason for port flapping is that you have different kind of devices connected to the same switch group. AP1 is in port 1 of the Mikrotik. AP2 is in port 2 of Mikrotik. BR0 consists of ports 1 and 2. MAC of AP1 is mapped to port 1 correctly. Intermittently though, in the bridge table of the Mikrotik, MAC of AP1 gets mapped to Port 2. This happens for multiple (if not all) MACs downstream from AP1 (bridge mode).Seen plenty of posts on the Mikrotik forums about port flapping and no solid resolution, even after Mikrotik 'acknowledged' it but 'couldnt reproduce' it. Only solution I have now is to grab some Mellanox ConnectX-3 cards off eBay which is cheaper than a much more expensive switch. An ongoing problem that I've had is port flapping of the ethernet port on the MikroTik that is connected to the Mimosa radio. When possible (not needing over 100 Mbps of speed) I've set the Mimosa radios to 100 Mbps (instead of Auto) and set the MikroTik routers to Auto at 100 Mpbs or 1000 Mpbs. This drastically reduces or eliminates the port flapping problem.The MikroTik RouterOS may function as a server or client – or, for various configurations, it may be the server for some connections and client for other.
