ModSnmp Manual v3.14 - 5.4. Saving and loading device types
The currently selected device type definition can be saved to a disk file by selecting the→ menu item. This displays a dialog that enables you to enter or select the name of the file to which the device type should be saved.
To load a device type from a file, use the→ menu item. This displays a dialog that enables you to enter or select the name of the file from which the device type should be loaded. If ModSnmp is "running" (i.e. the button is depressed), you will have to click the button before you can load the device type.
Device types are saved to files in XML format. There is, currently, no formal DTD (Document Type Definition) or XML schema for the format of these XML files. However, the format should be fairly evident to a human reader, and can easily be edited, if necessary, using a text editor.
