I have a 3750 switch that, every once and a while, all the lights go amber at once which blocks all ports for a few seconds. I am wondering if "spanning-tree portfast bpduguard default" has anything to do with this problem. I also have portfast turned on for each indivual port which does not connect to a switch.

What does the log say ?

I have swamped out the switch once and both times there have been no error messages in the logs.

Any errors reported on the interface ?

Uplink interface is clean and there doesn't seem to be any abnormal errors on any other interface.

Interesting, if the switch is blocking all ports, it sounds like a spanning-tree issue.
Do you have another switch connected to this switch ?
Can we see this switch config ?
