Overview
Contextual Intelligence Publisher can be configured to export syslog data in CEF, LEEF and Key-Value formats. The syslog data will help to correlate data in a syslog collector with device data from MetaAccess NAC.
Configure the Syslog collector
On the Syslog collector system, configure the MetaAccess NAC Policy Manager IP as a valid source of Syslog.
Configure CIP
Once the Syslog Collector has been configured, navigate to the MetaAccess NAC Configuration at https://portal.myweblogon.com:8443/manage (portal.myweblogon.com can be replaced by the manager IP or a branded URL) and choose “Contextual Intelligence.” Click on “Add” and enter the following information:
- Publisher: Syslog
- Name: A name to describe where CIP is publishing Data.
- Host: IP address of the Syslog Collector
- Port: listen port of the Syslog Collector
- Facility: Can be set to whatever is preferred in the Syslog Collector
- Level: Can be set to whatever is preferred in the Syslog Collector
- Format: The format best suited for you Syslog Collector
Once finished, click “Submit” and continue to the next section to verify the integration.
