I'm in Italy, Lombardy. Not snowing right now... Yesterday some cities arount my company plant had a full blackout (half an hour, but enough to exhaust all ours UPS).
So, at power return there was a supply transient (those UPS are scarce) and some switches fails.
Anyway, I'm sorry, but in Mudunes report, Inventory the faulted switch is provisioned, no SN.
Look at attached snapshot.
The device list is not enough, dont't forget how NeDi take care of 3750 stacks ad a single device.
I think that "inventory" shoud be a incremental table, with all devices and modules discovered, editable to correct some fields, and to delete substituted (replaced) devices or else.
Don't you agree?
