This sets, in seconds, how often the device automatically pushes collected RMON files to the configured server, with a range spanning from 1 hour up to a full year. This interval is a direct trade-off between data granularity risk and file-transfer overhead: too long an interval risks losing more RMON history if the device reboots or its local storage rolls over before a push happens, while too short an interval generates more frequent, smaller transfer jobs to manage on the archive server. For example, setting this to 86400 (24 hours) means a device that unexpectedly reboots could lose up to a day's worth of not-yet-pushed RMON history if local buffering doesn't survive the reboot.
