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?

[botswanamtc]

hello,

It is a cisco 3620.

[jdalrymple]

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.

Cisco Internetwork Operating System Software IOS (tm) 3600 Software (C3620-IO3S56I-M), Version 12.1(3a)T1

ip flow-export destination 10.x.x.x 9920

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.

[botswanamtc]

Yes I did but there is no change.

[jdalrymple]

I'm assuming the output you provided:

ip flow-export destination 10.x.x.x 9920

Is the results of the command I asked for?

show run | inc flow

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?
