Yesterday, I had serious problems on the my network. I have three switches on the my datacenter, one 3550 and two 2950, the ports of connection between them constantly disconnect. I see on the browser that the ports is on yellow color, informing that it was incapacitated, but I don't understand the cause. Who can help me? Can It disable ports because of intense traffic? Restarted the routers but the problem continued. Which tools I can use to monitor the imperfections and to decide the problem?
