Protection Engine for NAS 9.0.0 and later
The SPE 9.0.0 console has a limitation that "Interval must be between 2 and 24".
If you have not installed SPE in "Core server only mode", i.e., if you also use the SPE 9.0.0 console to change SEP settings, please take this limitation into account when configuring, even if you use the xmlmodifier command.
In "Core server only mode", i.e., when the SPE 9.0.0 console is not used to change SEP settings, the Liveupdate interval may be set with the condition "Any numerical value in seconds."
