This string holds the fully qualified Distinguished Name (Dn) that UCS Manager's information model uses as the unique address of this LAN Cloud FSM run. Because this LAN Cloud FSM run is the finite-state-machine record UCS Manager keeps while it actively pushes a LAN Cloud configuration change (such as a switching-mode change) through the fabric interconnect, its Dn is what scripts, XML-API calls, and cross-referencing objects (like another object's peerDn field) use to point straight at this exact instance rather than at a plain, possibly duplicated name. A value for this LAN Cloud FSM run might look like 'fabric/lan/fsm', with the exact segments reflecting where it sits under the fabric interconnect in the object tree.
