Abstract
For automatically identifying a failure in a logical circuit in a data network without manual intervention, the logical circuit includes one or more logical connections for communicating data in the data network. A network management module periodically requests trap data indicating the status of the logical connections in the logical circuit. After the trap data has been received by the network management module, the trap data is analyzed to determine whether any of the logical connections has failed. If it is determined that a logical connection has failed, the network management module may wait a predetermined time period to determine whether the failed logical connection has been restored. If after the predetermined time period the logical connection has not been restored, then the logical circuit is identified as having failed.
