NetFlow, IP Protocol 11 (NVP-II)

Unanswered Question

Hello -

I have NetFlow enabled on our router and we are experiencing high circuit utilization and NetFlow is reporting a lot of IP Protocol 11 traffic, when Google'd turns out to be NVP-II???

We have Cisco VoIP in the network, but this appears unrelated. Anyone else encountered this? Thanks for your assistance! =^)

I have this problem too.

Are you sure it's decimal 11 and not hex 11? Hex 11 is UDP which seems far more likely, especially as NVP is entirely obsolete.
