sflow issues on bsd

Apr 5, 2004, 1:54 PM

Post #1 of 5 (2254 views)

I have a bsd 4.9 computer with ntop 3.0. I am able to receive SFlows from
my switch but when I look at NTOP, the reports only show the actual packet
information of the flows and not what is in the flows. I was hoping to see
all the traffic from the switch instead of statistics on the flows. I used
the -F option to list my flow devices and I turned on sflow collecting in
the plugin menu. Does anyone have an idea of what I am doing wrong. I am
expecting to see a break down of ip traffic listed by the sflows.

HELP.

Thanks in advance.

Eric,
the sFlow implementation is based on some packets captured with tcpdump
that I have decoded using the plugin, as I have no access to a real
switch. It might very well be that you're using a version of sFlow that
is not supported by ntop as it is too new. Can you please mail me some
sflow packets captured with tcpdump (tcpdump -n -s 1518 -w file.dump and
mail me the file.dump file)?

Thanks, Luca

For this issue, should I try a different platform? Would it make a
difference? Linux maybe?

Hi,

Would a different OS like Linux make a difference? Would the Linux build
make a difference?

Thanks,

Eric

Ric,
it won't change anything. You need to provide me the sFlows you receive
in order to let me debug the problem.

Cheers, Luca
