Principal switch selection—This phase guarantees the selection of a unique principal switch across
the fabric.
Domain ID distribution—This phase guarantees each switch in the fabric obtains a unique domain

corresponding switch in the fabric.
Fabric reconfiguration—This phase guarantees a resynchronization of all switches in the fabric to
ensure they simultaneously restart a new principal switch selection phase.
