Cisco Stackwise

Hello ,

I have a doubt from config point of view of stack

  1. lets say we have 2 3850 switch that we are going to connect in a stack - do we need to configure both the switches with identical config OR just config one switch and other will automatically take the config?
  2. other than the stack cable between these 2 switch - what all we need to connect between them ? Ether-channel OR trunk ?
  3. whenever we config anything on master switch, same config will replicate on member as well ?

Thanks
Abhishek
