for 3 switches that are logically stacked together?
Not much information guide correctly-
what switch model - and what IOs Code running ?
what kind of stacking (physical stack cable or flex stacking )
If you confiured switch priorrity and switch number ( master switch should have all the configuration)
show switch show you forming the stacking, you can also view all the logs when the switches joined in stack.
you can also do testing removing master switch and see all the configuration synched to salve switch (if this pre-stage environment).
