Is it a Cisco ASA? If so you'll need to recompile nfcapd with nsel support.
Code: Select all
cd /tmp
wget http://sourceforge.net/projects/nfdump/files/stable/nfdump-1.6.13/nfdump-1.6.13.tar.gz/download
tar xzf download
cd nfdump-1.6.13/
./configure --enable-sflow --enable-nsel
make
make install
If not what type of device is it?

Wow - that goes back a ways.
1) What IOS?
2) Can you post the relevent portions of your config?
I think something like show run | inc flow will do it.

Did you do the download and recompile steps from a few posts back? I am referring to these:
Code: Select all
cd /tmp
wget http://sourceforge.net/projects/nfdump/files/stable/nfdump-1.6.13/nfdump-1.6.13.tar.gz/download
tar xzf download
cd nfdump-1.6.13/
./configure --enable-sflow --enable-nsel
make
make install
We usually see this issue with ASA devices, but it is entirely possible that other types/versions could require the same fix.

I'm assuming the output you provided:
botswanamtc wrote:ip flow-export destination 10.x.x.x 9920
Is the results of the command I asked for?

If that's the case you don't have flow enabled on any interfaces. You'll need to enable netflow on the interfaces you want to analyze.
Review our documentation:

Hello,
I have enabled netflow on the interfaces like I always do for other devices. My question is why is it graphing but the data is not visible.
Is there anything that I should look at on a device configs or what?
