I just installed a new Cisco 3560 Gigabit 48 port switch. Since it has been installed, at least once per day the LAN seems to lose connection for a split second (or long enough for our accounting system to lose connection to the database.) which requires a restart to re-gain connection. I have started a TAC case with Cisco but for the first time I am not getting very good service from them. Are there any ideas on what I can do to determine where the problem is. I have enabled syslogging and since then I haven't experienced the problem, I estimate it will happen sometime today and when it does I want to make sure the logging is configured correctly and it will capture the needed info.
