The MIB's DESCRIPTION for cucsLicenseInstanceFsmDescr is only the auto-generated stub 'Cisco UCS license:Instance:fsmDescr managed object property', but the 'fsmDescr' property name together with its SnmpAdminString type tell us this column, on a specific licensed-feature grant on a fabric interconnect (a feature name plus a quantity), holds the fsmDescr as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The fsmDescr is the current human-readable status text for this license instance's activation FSM, giving an admin a plain-English summary of what step the activation process is on without decoding enum values. This might read something like 'Activating license' while the underlying FSM is mid-flight.
