Ethernet flapping on RB3011

Hi guys, I have an issue with several RB3011 boards. Some ethernet ports are often flapping. For example, they go from 1 Gbps to 100 Mbps negotiation, or they disconnect unexpectedly for short times (1 -3 seconds). Of course this behaviour is causing lot of problems (I see frequent OSPF flapping bet...

thats' all!

I cannot see diagnostic info (datarate, signals, attenuation) but real speedtest is about 60/20 Mbps (same as previous router).
