We have a couple of RB3011s in our network that are handling OSPF on our towers. Everything was working fine until we swapped out our AF-5XHDs for AF-11FXs. Now every once in awhile all ports in the switch chip that the AF-11FX are connected to will disconnect for 2-3 seconds and reconnect. This happens a couple times a week. We have AF-11FX links that are connected into Cloud Core Routers as well in OSPF that do not have this issue. Has anyone else ever seen this? Literally the only thing that changed was the swap to the AF-11FX. I posted this over at UBNT as well.
Switch1 (ether1-5) or switch2 (ether6-10)?
Switch1
What version of RouterOS are you running?
There was an issue previously with port flapping when an 100Mb devices were connected.
