Hi,

we are using Netflow Analyzer 7.5 (7600) on a Linux Machine. The Software collects Data from Cisco Routers with Netflow and from Foundry/Brocade Switches with sflow.

Netflow in combination with the Cisco devices works fine.

The data from the Foundry/Brocade Switches doesn't fit together. Two Foundry SuperX with latest firmware are exporting sflow data for one 10Gbit/s Interface (this is the link beetween the two devices). If we compare the interfaces in Netflow Analyzer we will see 5,39GB Incoming Traffic on device 1 but only 37,35MB Outgoing Traffic on device 2. On the other side there are 21,54MB Outgoing on device 1 but 3,07GB Incoming on device 2 (see attachment). In my view, the data that will go out should come in on the over side.

What's the reason?

The switch configuration for sflow:

 slow-start 60 

interface ethernet 1/1
sflow forwarding

sflow version 5                                                  
sflow enable                                                     
sflow agent-ip 10.10.63.254                                      
sflow sample 128                                                 
sflow polling-interval 10                                        
sflow destination 10.10.10.10 9996    

Thanks for any comments!

(Please excuse my bad english)
