Abstract
A process or method for embedding diagnostic information in a Simple Network Management Protocol (“SNMP”) response during an occurrence of provisioning error is disclosed. A network element (“NE”), in one embodiment, is able to detect an operation failure while performing a GET or a SET request from a network manager. If the enhanced diagnostic code notification is registered between the NE and manager, the NE composes a response message such as GET-RESPONSE to include a standard error code as well as an enhanced diagnostic code. The enhanced diagnostic code includes diagnostic information associated with the operation failure. After transmitting the response to the network manager, the enhanced diagnostic code is subsequently decoded in accordance with enhanced diagnostic information stored in a network manager database.
