I believe that the names are check_ifstatus and check_ifoperstatus. check_ifstatus will check status of an individual router interface, while check_ifoperstatus monitors all interfaces in a router to determine if any are administratively up but operationally down. Not sure what type of gear you're using, but I think these checks may be for Cisco only.</DIV> Garry W.
