Regarding not working on 1.54 or newer, is that including the manual edit of the URL? I can get it to work on 1.58 with the manual URL edit, but i encountered a little bug if your filtering on the hostname field.
Ports WebGUI “hostname” field also searches sysName column in the DB.
However when you export to CSV (includes/html/reports/ports.csv.inc.php) matches this to the hostname column in the DB, which means you gain no results back if you are expecting this to search sysName.
Just in case anyone is filtering on that.
