Hi

The stacking configuration done automatically when you are connect the stack cable back side of the switch

the connection will be like this

switch 1 stack port 1 need to connnect switch 2 stack port 2

the same vise versa switch 1 stack port 2 need connect switch 2 stack port 1

If you want one switch always act as a master you can set the priority to the switch

conf t

switch 1 priority 5 ( you can set any number should be highest number in the stacked switches )

Hello Darren,

After stacking them, decide witch switch you want to be the master and give that one a higher priority. The priority is from 1 to 15 with 15 being the highest.

Also make sure you run the same exact IOS on both switches.

Please refer to this document for more info:
