This read-write enumeration (nil, saveDb, deleteSavedDb, deletePeriodicDb, revertToPeriodicDb, revertToSavedDb) lets an admin manually trigger a configuration database save or restore action on the ComController, where saveDb overwrites any previous saved copy and the revert options roll the active configuration back to a periodic or user-saved database. An admin uses it to protect against configuration mistakes before making risky changes. For example, before a bulk VLAN reconfiguration, an admin sets hcxDbAction to saveDb to snapshot the working configuration in case a later revertToSavedDb is needed.
