Managing Switch Stacks
When a new, out-of-box switch joins a switch stack, it uses the system-level settings of that switch stack.
If a switch is moved to a different switch stack, that switch loses its saved configuration file and uses the
system-level configuration of the new switch stack.
The interface-specific configuration of each stack member is associated with the stack member number.
As mentioned in the
unless they are manually changed or they are already used by another member in the same switch stack.

If a stack member fails and you replace with it with an identical model, the replacement switch
automatically uses the same interface-specific configuration as the failed switch. Hence, you do not need
to reconfigure the interface settings. The replacement switch must have the same stack member number
as the failed switch. For information about the benefits of provisioning a switch stack, see the
Stack Offline Configuration" section on page
You back up and restore the stack configuration in the same way as you would for a standalone switch
configuration. For more information about file systems and configuration files, see
"Working with the Cisco IOS File System, Configuration Files, and Software Images."

If an interface-specific configuration does not exist for that member number, the stack member uses
its default interface-specific configuration.
If an interface-specific configuration exists for that member number, the stack member uses the
interface-specific configuration associated with that member number.
