Description

For version 9 flows, a 32-bit value that identifies the Exporter Observation Domain is called the source ID. NetFlow collectors use the combination of the source IP address and the source ID field to separate different export streams originating from the same exporter.

MX and QFX Series: Typically, this attribute is used to limit the scope of other information elements. If the observation domain is not unique, the collector cannot uniquely identify an version 9 device. If you configure the same source ID for different template types, such as for IPv4 and IPv6, it does not impact flow monitoring because the actual or the base source ID is transmitted in the flow. The actual source ID is derived from the value you configure and plus other parameters such as the slot number, lookup chip (LU) instance, and Packet Forwarding Engine instance. Such a method of computation of the observation domain ID ensures that this ID is not the same for two version 9 devices.

PTX Series: When you configure the source ID, the software attaches the ID to a particular template type. If you configure the same source ID for two different template types, such as for IPv4 and IPv6, this does not impact flow monitoring, because the configured ID is not what is being sent. The value sent in the packets is derived from that configured value and the FPC slot value. This method ensures two version 9 devices can never have the same value of observation domain ID.
