This enumerated field (CucsFabricConfigState) reports the current configuration-application state (e.g. applied, failed, applying) for one physical port that is a member link of a NAS-storage-connectivity (Estc) port-channel. This is the value an admin checks on this NAS-storage port-channel member port right after pushing a change, to confirm the fabric interconnect actually finished applying it rather than leaving it stuck mid-configuration. A value of 'applied' means the last configuration change succeeded; 'failed-to-apply' would flag a change that didn't take on this specific object.
