Cluster database instances should use private interconnects for internode communication. This metric monitors whether the network interface used by the cluster instance is a private one. If the network interface is known to be public, a critical alert is generated. If the network interface type is unknown, a warning alert is generated.
The rest of the information in this section is only valid for this metric when it appears in either the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable).
The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

The instance is using interface '%if_name%' of type '%value%'. |
For this metric you can set different warning and critical threshold values for each "Interface Name" object.
If warning or critical threshold values are currently set for any "Interface Name" object, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each "Interface Name" object, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.

Use oifcfg in the CRS home to correctly configure the private interfaces in OCR.
