Abstract: Displaying a network topology map may include creating a database representing objects in a network; requesting a topology map of a certain type to represent at least a portion of the network; determining from the database a set of objects corresponding to the type of the requested map; determining parameters associated with the map type; and, while the cardinality of the set is above a threshold: presenting at least one of the parameters on a display, enabling a user to specify a value or group of values for the parameter, and reducing the cardinality of the set by removing objects not matching the value or group of values specified for the parameter.

Abstract: A method and system is disclosed for automatically discovering Cisco Discovery Protocol (CDP) nodes a network in real time. The discover process transmits a signal from a network manager to a first CDP node of the network. The signal requests information regarding additional CDP nodes known to the first node. The network manger receives a response is that identifies additional CDP nodes known to the first CDP node. The transmitting and receiving steps are then repeated for each additional CDP node identified. A list containing information of all identified nodes is then stored.

Abstract: A method and system are described for presenting an arrangement of management devices operable in a managed network. According to exemplary embodiments, a number of management devices arranged in the managed network are identified. Identities of the management devices are presented in a graphical user interface (GUI). Visual cues are added to the GUI to identify a communication status between a first of the management devices and each of the remaining management devices arranged in the managed network. A software link can be provided between each presented identity and the respective management device to provide automated access to management information maintained at the respective management device. A graphical representation and an operational status of a portion of the managed network can be presented based on the management information maintained at the respective management device in the GUI via the software link.

Abstract: A method and system are described for presenting neighbors of a device in a network via a graphical user interface. According to exemplary embodiments, a determination is made for a segment of the network that includes the device whether a connecting device is coupled to a corresponding connecting device included in another segment of the network. Identities of the device and the coupled connecting and corresponding connecting devices are presented together with visual cues identifying a connectivity among the presented identities in the graphical user interface.

Abstract: A network management node monitors network attributes of a network. The network management node is connected to network devices through the network and receives data values associated with measured network attributes from said network devices. The data values are stored in the network management node and a baseline value and rearm baseline value for a network attribute are calculated from a plurality of the received data values measured during a first period of time (e.g., a first time bucket). These data values are compared to the baseline value, and an alarm is generated in response to at least one of these data values exceeding the baseline value. The alarm is reset if at least one subsequently measured data value is below the rearm baseline value. The baseline value and rearm baseline value are recalculated from received data values measured during subsequent time buckets. Data values measured during the subsequent time buckets are compared to corresponding baseline and rearm baseline values.

Abstract: A network management tool operable to display a visual representation (e.g., a network topology) of network devices monitored by the network management tool is disclosed. Network management software (NMS) is executed on a network management node for monitoring one or more networks. The NMS includes a display module and a filter module. The filter module allows a user, such as a network administrator, to select a plurality of filters that limit the information provided in the visual representation. The network administrator may select filters associated with particular types of nodes and/or status levels of the selected nodes. Information associated with the selected filters may be retrieved from a database containing information about the nodes in the monitored networks. The display module creates the visual representation using the retrieved information. The visual representation is divided into segments, and the visual representation may be displayed on a single display page.

Abstract: A method and system is disclosed that transmits a signal from a network manager to each of plural nodes to determine the availability of each node. A response time of each node is determined using the signal. The response time of each node is then relayed to a database of the network manager. Optionally, the response time which is received in a standard format is converted into a flat file format.
