Logging flow monitoring records with version 9 and IPFIX templates for NAT events

You can configure the router to log network address translation (NAT) events using the Junos Traffic Vision (previously known as Jflow) version 9 or IPFIX (version 10) template format. NAT event logger generates messages in flow monitoring format for various NAT events, such as the creation of a NAT entry, deletion of a NAT entry, and for invalid NAT processing (such as NAT address pools or address values being exhausted for allocation). These events also support NAT64 translations (translation of IPv6 addresses to IPv4 addresses), binding information base (BIB) events, and more detailed error generation. The generated records or logs for NAT events in flow template format are sent to the specified host or external device that functions as the NetFlow collector. Previously, MS-PIC uses the system logging protocol (syslog) to generate session logging. System log messages can be sent directly from the MS-PIC to an external system-logging server. For this transmission of syslogs to work properly, the services PIC interface must have an IP address and appropriate system logging options configured.
