Configuring SDN and SD-WAN Polling Settings

The following devices are supported for SDN and SD-WAN Polling settings:

• Cisco ACI
• Cisco Meraki
• Cisco Viptela
• Juniper Mist

To enable or disable the SDN and SD-WAN polling globally and to define mapping rules for network views for these devices, click the Settings icon > Setup > SDN/SD-WAN Polling. If SDN and SD-WAN polling are disabled, only SNMP/CLI 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 the supported devices, you can select different modes for mapping 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, do the following:

1. Click the Settings icon and go to Setup > SDN/SD-WAN Polling.
2. Select Enable SDN/SD-WAN polling.
3. Specify Default SDN Network View: This network view will be assigned to discovered devices for which the automatic mapping of network views is disabled. You enable or disable automatic mapping in the Advanced panel. 
4. In Network View Mapping, select one of the following:
   
   • Disable automatic mapping and use predefined SDN Network View: Select this option 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 this option to automatically map collected networks to their network views by using internal rules for NetMRI. 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 it 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. Click the Settings icon and go to Setup > Collection and Groups > Switch Port Management.
   2. Specify one of the following:
      • Periodic Collection: Specify the time N (in minutes or hours) a collection is to occur.
      • Scheduled Collection: Schedule collections to take place hourly, daily, weekly, or monthly.
6. Click Save.
