This variable allows configuration of a stack
fragment created by a stack split.
When set to 'true (1)' in the greater fragment, the
physically present members of the current stack
become the only members, and the configuration of
the missing members is converted to strict
provisioned configuration.
When set to 'true (1)' on a lesser fragment, the
existing stack information is cleared and a new
stack ID is created. The switches in the stack will
become 'active' and retain their configuration.
No action is taken when set to 'false (2)' in any
stack.
