Description: The value of ctDLFileName during the last successful image download. This is the name of the file, on the TFTP server, that was download to become the current image.
What is ctDLLastImageFilename?
This records the filename that was actually used the last time an image download completed successfully, mirroring the value of ctDLFileName at that time. It gives an admin an audit trail of what firmware image is genuinely running on the device right now. For example, seeing "switch_fw_v6.1.bin" here when the admin believed v6.2 was loaded reveals that the more recent upgrade attempt actually failed.
