Configuration files are changed only through explicit user configuration, and are not automatically modified when units are added, removed or reassigned unit IDs. Each time the system reboots, the Startup Configuration file in the Master unit is used to configure the stack. Managing Configuration Files on the Stack The Startup Configuration and Running Configuration file are stored on the stack master.
