## Symptoms

- NetFlow statistics show switched SRC IP and DST IP connections: the SRC IP is the DST IP, and vice versa.


For example:

```

If the connection is: 
SRC -> 192.168.32.98 DST-> 10.26.2.63
The statistics show:
SRC -> 10.26.2.63 DST -> 192.168.32.98
```

<br />

## Cause

NetFlow generates two records for each connection: C2S and S2C. For S2C, the addresses are reversed.
