5.1.5 Management address preferences
A node's management address is the address NNMi uses to communicate with the node's SNMP agent. You can specify the management address for a node (in the specific node settings), or you can let NNMi choose an address from the IP addresses associated with the node. You can fine-tune this behavior in the discovery configuration settings by excluding certain addresses from discovery. For details about how NNMi determines the management address, see Node Form in NNMi Help.
- Note
-
To discover hypervisors NNMi requires the node name rather than the management address.
NNMi discovers and monitors devices on an ongoing basis. After the first NNMi discovery cycle, the Enable SNMP Address Rediscovery field controls NNMi behavior when previously discovered SNMP agents quit responding (for example, when you reconfigure the device's SNMP agent).
If the Enable SNMP Address Rediscovery check box is selected, NNMi retries any configured values in search of one that works.
If the Enable SNMP Address Rediscovery check box is cleared, NNMi reports the device as Down and does not attempt to find another communication configuration setting for that device.
The Enable SNMP Address Rediscovery check box is available at all levels of communication configuration.
The Discover Any SNMP Device and Discover Non-SNMP Devices auto-discovery rule configuration fields influence the way NNMi uses SNMP. For details, see Configure Basic Settings for the Auto-Discovery Rule in NNMi Help.
