I have a Cisco 3550 48 port switch which as begun to experience packet loss leading to connectivity issues to my network in the last 3 days. The problem comes and goes and has varing levels of severity. I have booted the switch botted the media converters on both ends of the fiber connection. I can generally see in to this switch and its VLAN, but dependant upon the severity of the packet loss cannot always see back home. Looking for suggestions on how to troubleshoot this problem.
