An accessible-for-notify enumeration of the possible configuration-conflict types (such as area mismatch, Hello or dead-interval mismatch, MTU mismatch, or duplicate router ID) carried in OSPFv3 config-error notifications; it reads back as 'noError' if no such notification has fired yet. This value is what tells an operator receiving an hwOspfv3IfConfigError trap exactly what kind of mismatch was detected.
