This CucsFabricConfigState field reports whether the configuration requested for this direct-attached FC storage port has actually been applied to the hardware yet. For one physical FC port on the fabric interconnect that is a member of a direct-attached (non-SAN-switch) external storage connection, this matters because a config change submitted in UCS Manager is not instantaneous — this field is how an admin confirms the change on this specific connection actually took effect rather than silently failing to apply. A value of 'applied' means the last configuration push succeeded; 'failed-to-apply' would tell an admin to look at the associated fault for why this particular connection rejected the change.
