Cisco Cisco IOS Software Release 12.2(27)SBC

The value of the top label is 12305.

The experimental bits value is 6 and the end-of-stack bit is 0.

The value of the second label is 12312, the experimental bits value is 6, and the end-of-stack bit is 1.

To fully understand and use the information gathered on the P router, you need information from the 
Label Forwarding Information Base (LFIB) on the PE router.

The MPLS application owner for a label is not reported by MPLS-Aware NetFlow for any MPLS label; 
only the label number is reported. If you are interested in identifying the MPLS application owner for 
MPLS labels, you need to configure the NetFlow MPLS Label Export feature on your network devices. 

Using MPLS-Aware NetFlow and NetFlow MPLS Label Export together, you can monitor various labels 
in the MPLS label stack by exporting the information to a NetFlow collector for further processing with 
a data analyzer and look at MPLS traffic patterns in your network. 

MPLS-Aware NetFlow captures and reports on per-flow statistics for both incoming MPLS and IP 
traffic: 

For MPLS traffic, MPLS-Aware NetFlow captures and reports up to three labels of interest, along 
with a subset of NetFlow data.

For IP traffic, MPLS-Aware NetFlow provides the regular NetFlow data. 

MPLS-Aware NetFlow uses Version 9 format to export both IP and MPLS NetFlow data.

MPLS-Aware NetFlow provides the following traditional NetFlow per-flow statistics:

Number of packets

Number of bytes, counting either MPLS payload size only or MPLS payload size plus MPLS label 
stack size

Time stamp of the first packet

Time stamp of the last packet

In addition to these statistics, MPLS-Aware NetFlow exports values for the following fields for each 
flow, using Version 9 NetFlow export format:

Regular NetFlow fields:

Source IP address

Destination IP address

Transport layer protocol

Source application port number

Destination application port number

IP ToS

TCP flags 

Input interface

Output interface
