The MIB's DESCRIPTION for cucsLicenseFileFsmCurrentFsm is only the auto-generated stub 'Cisco UCS license:FileFsm:currentFsm managed object property', but the 'currentFsm' property name together with its CucsLicenseFileFsmCurrentFsm type tell us this column, on the finite-state-machine record that tracks a license file's install/validation workflow, holds the currentFsm as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The currentFsm names which specific state machine is currently driving the finite-state-machine record that tracks a license file's install/validation workflow — UCS Manager runs different named FSMs for different license operations (e.g. installing a file versus activating an instance), and this field tells you which one is active right now. During a license-file install this might read something like 'LicenseFileInstall', switching to a different named FSM once installation finishes and activation begins.
