    Abstract: Disclosed are systems, methods, and computer-readable media for assuring tenant forwarding in a network environment. Network assurance can be determined in layer 1, layer 2 and layer 3 of the networked environment including, internal-internal (e.g., inter-fabric) forwarding and internal-external (e.g., outside the fabric) forwarding in the networked environment. The network assurance can be performed using logical configurations, software configurations and/or hardware configurations.

    Abstract: Systems, methods, and computer-readable media for detecting and reporting anomalies in a network environment for providing network assurance. In some embodiments, a system can determine confidence scores for at least one value of parameters of a network environment defining network events occurring in the network environment. The confidences scores can indicate a frequency that the defined network events have a specific event state. The confidence scores can be monitored to detect an anomaly in the network environment. In response to detecting the anomaly in the network environment, the system can determine a relevant network state of the network environment. The relevant network state of the network environment and the anomaly in the network environment can be presented to a user.

    Abstract: Systems, methods, and computer-readable media are disclosed for validating endpoint information for nodes in a network. A network assurance appliance is configured to retrieve an actual tunnel endpoint address for an endpoint in communication with a network fabric via a leaf node in the network fabric, identify a reference tunnel endpoint address for the endpoint, and determine that there is an inconsistency based on a comparison of the actual tunnel endpoint address with the reference tunnel endpoint address.

    Abstract: Systems, methods, and computer-readable media for clustering events occurring in a network environment for providing network assurance. In one embodiment, a system can identify event states of network events defined by values of parameters of a network environment. The system can determine a confidence score that at least one of the values of parameters is associated with a specific event state using the network events and the identified event states of the network events. The confidence score can be presented to a user for purposes of providing network assurance for the network environment.

    Abstract: Systems, methods, and computer-readable media are disclosed for validating endpoint information for nodes in a network. A network assurance appliance is configured to retrieve first endpoint information about endpoints in the network from one or more spine nodes in a network and second endpoint information about the endpoints in the network from one or more leaf nodes in the network. The network assurance appliance compares the first endpoint information with the second endpoint information and generates an event based on the comparison.

    Abstract: Systems, methods, and computer-readable media are disclosed for validating endpoint information for nodes in a network. A network assurance appliance is configured to retrieve a configured static endpoint information in a logical model of a network from a network controller and connected static endpoint information from one or more nodes in the network. The network assurance appliance determines that there is an inconsistency based on a comparison of the configured static endpoint information and the connected static endpoint information and generating an event specifying the inconsistency.
