We are having an odd issue in which a 2950 we have plugged into a 6509 is inaccessible. A reboot was done and after it was rebooted, the management interface on vlan999 is inaccessible via telnet or ping. If we move the management interface to a different vlan/subnet the switch is accessible but very slow to access. We noticed the throttles are incrementing and the packets per second are above 150. We duplicated this issue when connecting to a whole different 6509 chassis on the same LAN campus. We plug into a distribution 4000 or 350012G switch and the problem goes away. Any ideas? We are checking sources of traffic but interested to see if anyone out there has ran into this and what the resolution was found to be. The switch is passing traffic, and if we put a workstation into the same vlan on that switch it can get anywhere in the network as well as ping the switch that is malfunctioning.
