NetFlow, IP Protocol 11 (NVP-II)

[brobinson]

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! =^)

Hi,

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.

HTH

Andrew.

LOL! You are correct. That totally blew past me. I was looking at TCP in hex, but not 11 for some reason. Oh well, it was late. Thanks!!!
