Netflow on HP5400 showing more sources than configured

Hi there

We have an HP 5400 that we have enabled netflow on 2 ports, however when I look into NTA on Orion I see Netflow received on 5 ports on this device

Can anyone shed some light on the configuration for the 5400 with regards to NetFlow as its got me stumped right now

Hi randomguy,

each flow carries information about 2 interfaces - input and output. By default NTA has 'Enable automatic addition of NetFlow sources' option turned ON, that's why some interfaces were added automatically (you should see appropriate messages on Last 25 events resource).

If you don't want this interfaces to be automatically added to NTA monitoring, please navigate to Admin -> NetFlow Settings and check this settings:

Enable automatic addition of NetFlow sources - OFF

Allow monitoring of flows from unmanaged interfaces - ON

thanks

Further to this, when I drill into the other ports that we haven't set netflow on we don't see any data....
