Updates to network model mappings are sent automatically from the ArcSight Manager to SmartConnectors within heartbeat messages. The heartbeat messages themselves are sent on an interval which can be anywhere from every 5 seconds to every 10 minutes, but network model mappings are included in the messages only when there are updates to the model.
Note: The interval on which information is exchanged between the Manager and SmartConnectors is determined by the Heartbeat Frequency setting on each Connector. (See information on Heartbeat Frequency in default content tab configuration fields under Selecting and Setting SmartConnector Parameters.)
If you have made several configuration updates to the network model on the Manager and would like these changes to take effect immediately on the SmartConnectors without waiting for the next automatic refresh, you can use the following command to send the update information to a selected Connector.
Where: Navigator > Resources > Connectors
To send model mappings to SmartConnectors:
Right-click the SmartConnector you want to update and choose Send Model mappings now.
This sends information about the current network model mappings from the Manager to the selected Connector. It forces a comprehensive refresh of the zone mappings and network model information on the Connector.
