vlan dynamic disaggregation
one of our netflow generators is sending flows for multiple vlans. I have
picked out a few of the packets to show:

Here is the template it is sending:

Here is a sample packet received for vlan id: 0
[image: image.png]

And here is one received for vlan 95:
[image: image.png]

I select Vlan Id for dynamic disaggregation:

Then restart ntopng. The only thing I see in the interface drop down is
for vlan 0. Not vlan 95.

Any help would be appreciated.
Thanks.

Hi Munroe
can you please file a ticket on github with this information and attach the configuration you are using?

IMHO seeing a zero flat image means that you have problem receiving flows. The issue is there IMHO.
