The file system device for which files will be displayed in the FileViewer table. The values supported for this variable are identical to the values for other variables in the MIB, although not all values will actually result in the display of files. The different devices and whether they will result in the display of files are: 1. Flash - Onboard Flash - supported 2. Card - Removable SD card - supported 3. NVS - Onboard battery backed RAM - supported 4. TFTP - not supported 5. USB - Removable USB media - supported Note: Card and USB are supported on the stack master or Active CFC. The devices cannot be read if atFilev2FileViewerStackId is set with the ID of a different stack member or chassis card. Setting this variable to an unsupported value will result in an error, but setting to a value that is supported but on a system that doesn't contain that type of device will not. However, no files will be displayed in the File Viewer table in this case.
