Sbastia,   Would you confirm a few things for me?   Just to be certain, these are PowerConnect 6248?   How many switches are there and are they all the same model?   Is this a new configuration, if so has this ever worked without the issue you're describing? If it is an existing configuration when did this issue start and was anything done on the switch prior to the issue in question?   If need be, could you private message me your full running-config?   Let me know and we can go from there.
