Recreate external data groups on a test LTM to test another LTMs

The file will download with the strange file name. You can rename it (before importing) to eliminate the ":Common:" part as well as the random number and version suffix parts.

 

Also, did you edit the file at all between the time you download it from prod and imported it to test? The format of the file can be touchy, depending on the editor. (I use Notepad to avoid automatic insertion of all kinds of crazy coded information at the end of the line, as Word has a tendency to do.) There should be a comma at the end of each line and just a new-line character (\n) not a full CRLF (\r\n). There are some examples here. You can check for errant line feed characters in the file using:

 

cat | od -c

 

If you see both \r\n in the output, run this command to remove the "\r" characters:

 

tr -d "\r"

 

 

Lastly, you have to make sure you set up the File Management Data Group object name to be the same as the file name specified in the associated iRule Data Group object. The two tie together. Otherwise I expect the config won't load properly.
