The MIB's DESCRIPTION for cucsLicenseFileOperStateDescr is only the auto-generated stub 'Cisco UCS license:File:operStateDescr managed object property', but the 'operStateDescr' property name together with its SnmpAdminString type tell us this column, on an uploaded UCS license file, holds the operStateDescr as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). This holds the human-readable explanation that accompanies operState, spelling out in text why a license file installation succeeded or failed (e.g. host ID mismatch, bad signature) rather than just a numeric or enum code. If a file was uploaded for the wrong fabric interconnect, this field might read something like 'Host ID mismatch' instead of a bare failure code.
