The MIB's DESCRIPTION for cucsLicenseInstanceFsmStageDescrData is only the auto-generated stub 'Cisco UCS license:InstanceFsmStage:descr managed object property', but the 'descr' property name together with its SnmpAdminString type tell us this column, on one stage inside that license-instance activation FSM, holds the descr as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The descr is the text name of this one stage inside the license-instance FSM's step-by-step sequence (each FSM breaks its work into ordered stages, and this string names which stage this row is). A stage might be named something like 'InstallLocal' or 'Verify', identifying exactly which step of the license workflow this row reports on.
