Description: Contains the configured software image to be downloaded to the ComPort. The Common Controller download process shall check this value when a download is requested. If this image does not support the hardware specified by the ComPort then an incompatible software version trap shall be generated. It is then up to the user to correct this field. When this field is set, the agent shall check if there is an image of the specified type loaded. If this is not the case then a unavailable software version trap shall be generated. Again, it is the responsibility of the user to ensure that the required image is downloaded. The image identifier shall be represented by 4 numbers deliminated by periods. i.e. a.b.c.d. Each number shall have a value between 0 and 255. This allows storage within a single (four byte) word.
