Configuring SDN and SD-WAN Polling Settings

To enable or disable the SDN and SD-WAN polling globally and define network view mapping rules for Cisco Meraki, click the Settings icon > Setup > SDN/SD-WAN Polling. If SDN and SD-WAN polling is disabled, only traditional network devices are polled.

You can also modify the end host collection interval for SDN and SD-WAN. Controlling the polling setting and end-host data collection allows you to reduce the load on your system if required.

For Cisco Meraki devices, you can select between different modes for mapping Meraki networks to NIOS network views. This mapping mechanism is required as your Meraki infrastructure may have overlapping IP ranges that can be supported under different network views. The mapping rules include the following:

• Mapping to the predefined SDN network view
• Automatic mapping
• Custom mapping

To configure SDN/SD-WAN polling settings, complete the following:

1. Click the Settings icon > Setup > SDN/SD-WAN Polling.
2. Select Enable SDN/SD-WAN polling.
3. Default SDN Network View: The network view that will be assigned to discovered Cisco Meraki devices for which the automatic network view mapping is disabled. You enable or disable automatic mapping in the Advanced panel. For more information, see the step below.
4. In Network View Mapping, select one of the following:
   
   • Disable automatic mapping and use predefined SDN Network View: Select to map collected SDN/SD-WAN devices to the default SDN network view defined in the previous step.
   • Automatically create network views for unmapped networks: Select to automatically map collected networks to their network views using NetMRI internal rules. Network views that do not exist are created automatically. The mapped networks are displayed in the table that is not editable.
   • Enable network view mapping defined below: This is custom mapping. Select this to manually map collected networks to the appropriate network views. To change a network view entry, double-click it in the table.
5. If necessary, override the global data collection interval that will be applied to the SDN/SD-WAN host polling:
   1. Go to the Settings icon –> Setup –> Collection and Groups –> Switch Port Management.
   2. Specify one of the following:
      • Periodic Collection: Specify the N minutes or hours when the collection should occur.
      • Scheduled Collection: Schedule recurrent collection based on hourly, daily, weekly, or monthly time periods. Click one of the tabs, Once, Hourly, Daily, Weekly, or Monthly to choose a recurrence pattern.
6. Click Save.
