About 4 months ago or so I had what I though was a firewall problem, tuned out to be two bad switches or so I thought. I replaced the switches with 3 com switches and everything seemed fine. Until Monday, my network was down again I though because I had a patch cable plugged into the same switch because when I took that patch cable out of the picture and reboot the switches everything seemed good. Then Tuesday I installed a new Cisco 2960 to help relieve some of the stress on a switch. Then I plugged in another 2960 and started checking out the network assistant and monitoring tools but every time I clicked refresh or just clicked on the newer of the two 2960s the network connection would bounce? Now today the switch that had been in production the 3com just started to bounce its connection on and off ? I had to plug everything into the new 2960 and unplug the 2nd 2960 to keep the network stable, well its only been about a half an hour.
What am I missing? Is it a timing thing? Are the switch trying to sync speeds with each other?
