This OID reports, as a Gauge32 numeric code, the error code returned by the last remote invocation made while running the workflow tracked by an ImportRootFsm object — the finite-state-machine record that drives the workflow of one ImportRoot configuration-import operation from start to finish. An admin or Cisco TAC uses this code (together with the matching error-description field) to identify exactly which remote call failed inside the ImportRootFsm workflow, instead of treating the whole operation as one opaque failure. For example, a non-zero value here alongside an otherwise-successful-looking ImportRootFsm record is the signal to open the paired rmtErrDescr field for the human-readable explanation of what that remote call rejected.
