I'm about to do a port mirror to see whats going on with that. Every port on every switch blinks at the same time as fast as they can. I don't see any issues with spanning tree changing. I did some netflows and don't see anything out of the norm with that. Hopefully port mirror will shed some light.

I'm running cisco 2960's all over. if all the usual things are okay - ie spanning-tree is stable, there are no links going up/down, you have eg portfast for edge devices etc etc then perhaps all you are seeing are the usual busy lights for cisco LEDs - what sort of rapid blinking? all blinking at same time? have you done a port-mirror of the uplink to see what is really going on? alan _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
