Cisco Cisco IOS Software Release 12.2(27)SBC

With the exception of the input interface and output interface fields, these regular NetFlow fields 
are not included in a flow if the no-ip-fields keyword is specified in the ip flow-cache mpls 
label-positions command.

Additional fields:

Up to three incoming MPLS labels with experimental bits and an end-of-stack bit

Positions of the three labels in the label stack

Unlike NetFlow, MPLS-Aware NetFlow reports a 0 value for IP next-hop, source and destination BGP 
autonomous system numbers, or source and destination prefix masks for MPLS packets.

If you are exporting MPLS data to a NetFlow collector or a data analyzer, the collector must support 
NetFlow Version 9 flow export format, and you must configure NetFlow export in Version 9 format on 
the router. 

For more information on IP NetFlow, refer to the 

Cisco IOS NetFlow Configuration Guide, Release 12.4.

 shows MPLS-Aware NetFlow full and sampled NetFlow support. Information in the table is 

based on the Cisco IOS release and includes the commands to implement the functionality on a 
supported platform.
