Hey! Something inexplicable happened tonight and something that I could not find the reason for, so I ask for help and new ideas.
In the office, CCR2004-1G-12S + 2XS works as the main router. Firmware 6.47.9 LongTerm. Tonight under load without any reason, in the absence of external intervention (limited access to equipment) and excluding power problems (2 UPSs are involved), all ports turned off in turn and turned on after 2 seconds. I attach a full record of the logs.
I draw your attention to the fact that the port speed is partly Auto Negotiation, and part is set manually. The SFP ports use both proprietary SFP modules and noname. There are several Cisco and TP-Link DACs.
Any idea why this might have happened?
A similar thread from a few days ago:
But in this topic, the problem has not been solved and is only slightly similar to mine. I think that my problems and in the next topic are different. Support cannot help me yet
The CCR2004 has issues, so you might be out of luck for now until new software becomes available.
We have had the same problem here some days ago, all ports flapped.
I think these guys cracked it: http://forum.mikrotik.com/t/rb5009-all-connected-ports-flap-a-few-times-a-day/155042/1
My CCR2004+12G also flapped initially when I was setting it up and kept eyes on things - my etherner ports flapped 3 times in 12 hours that day. Each time one block of ports (so six of them) flapped.
Now I keep DHCP table closed unless I actually need it and I never have an issue with ports! And I notice that table kept freezing a lot, unlike any other Winbox menu.
