Our client has two routers with 4 serial connections to each other and configured to be members of multilink 1. Problem is, one serial connection went down but didn't send out email notification to the client. It did create a log though on Device Center as well as on Alerts and Activities under DFM. I've checked out on DFM under Device Management>Device Details that all serial interfaces that are part of the multilink 1 is set as "true" under "Is Managed". Is there something wrong with my notification groups or event set perfaps that it didn't sent out email notification? Need your advice on this.
