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?
