2.9.1.1. Generic
The Generic tab is the first option of the Configuration vars menu.

In this tab we can modify the following configurations :
Interval to persist ‘last change’ updates to DB (in seconds), we can set the time to include events in the database (by default, 1800 seconds). This optimization is created to avoid the same events with same source IP, destination, the policy used and so on.
Allow access to the API Documentation and the access link to the API Doc
Enable the flag to return VLAN as name instead of VLAN ID, OpenNAC Enterprise allows to work using VLAN names instead of using VLAN Ids, is possible to define VLANs name in the switches such as SERVICE VLAN and send this stream instead its VLAN ID.
Configure the Kibana IP and its port. It allows us to set the IP address for the ON Analytics server, the Kibana’s port is 5601 (normally it is not required to be changed)
Dashboard Home path.
Add additional info in the About section, located in the bottom left corner of the interface, to identify the product’s version and license type.
Enable SNMP Trap monitoring, allowing to the ON Core to read SNMP Traps register and use network events.
Click Save to apply the changes.
