Dennis, In large installations, I've always found it helpful when diagnosing LAN issues to isolate floors and departments first - using routers or with devices that can do transparent bridging. That way, you can walk through each dept/floor testing for the issues, and hopefully find only one location its still affecting.
Its entirely likely that there's either a loop of some sort or a switch has gone off the deep end. If you'd like, let him know if he wants to drop me a mail, I can walk through details about the situation and hopefully help him narrow it down. ------Original Message------ From: Dennis Dayman To: nanog@nanog.org Subject: Latency quesstion Sent: Mar 18, 2010 7:56 AM have a friend who has 21 floors of a building in DFW, multiple switches, etc and they started to have latency issues this weekend where half if not all packet are being dropped to folder shares, printers, etc. Suggestions on how they can troubleshoot that? call in a company to help identify it? -Dennis -- Brielle Bruns http://www.sosdg.org / http://www.ahbl.org
