I have a small SG300-8 switch to connect 1Gbps Internet Connection to a router and a server console. Today we have suffered a network outage and I don't know the reason and if it has been related with the switch model.
Since this afternoon I have a great number of packet losses between the ISP and our switch. So many losses that I couldn't connect to any device (switch, router, service console) from Internet and we have completely lost internet connection. The ISP have told me that he was receiving a great number of input errors (mainly CRC errors) in his network interface. But suddenly it has begun working again.
I have only these logs from the switch and I'm very worried about this problem. The logs of the switch:

The only thing that I don't understand is the meaning of "agregated". The port gi2 is where ISP was connected. I would appriciate any comment, any! Thanks is advance, I would try to sleep...
