We just configured Flexible Netflow on Cisco router but on NFA console no Data is visible.When check on Interface tab and tried to refresh we are getting error
"Refresh Failed, could not poll deviceThe maximum message size quota for incoming messages (1000000) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.".
Though Netflow command enabled on only 3 physical interface , we could see more than 6000 interface .
Any help/support is appreciated.
What version of NFA?This could be due to a large amount of interfaces on this device.
SNMP Polls will look for all interfaces on the device.
NFA 9.3.0 and newer filter out Non Netflow IfType's so it will not have to poll as many interfaces, and should prevent this problem.
NFA version 9.2.1
Customer enabled Flexible Netflow command on 3 Physical interfaces but NFA showing 6K interface .
I am trying to update same today with 9.3 SP1 .
9.3.1 should fix this, as it will ignore interfaces with an ifType that would normally not have NetFlow data and limit the number of interfaces return in the poll to a manageable number.
The doc below explains this in more detail...

If you were to stay on 9.2.1 you could also apply the patch documented in this doc....

I re-Installed the fresh copy of NFA 9.3.1 and tried checking the NBAR2 info but no luck ..
Router which was configured with FNF commands initially shows utilization for IN & Out but after few minutes it stop showing out interface data…
Looks like FNF /NBAR2 command somewhere causing the problem.
We are still researching on commands .Hope thing works…
Not sure if we have a LAB where we can actually enable the FNF /NBAR2 commands and see all those information .
So this is a different problem now, this should be in its own thread.
In order to see NBAR2 data you need to import the nbar2.csv as per the Admin guide.
Also the device needs to be properly configured. The document below has a sample NBAR2 configuration.
