NetFlow Sources

brentbo over 9 years ago

Any ideas why a node would be listed as a NetFlow source in the NTA module when the device is not configured with NetFlow? Selecting the node in the Flow Navigator, there is no NetFlow data associated with the node (of course), but it is listed as a source with two source interfaces, a Multilink and Serial interface. I can look at the config of the node in NCM and the word 'flow' is not in it. Signed Confused in Sacramento.

Well, a node will be listed in NetFlow sources in case you've been receiving data from in past or if you've checked to receive NetFlow/CBQoS from this node in Manage sources.
To get rid of it (in both cases), please go to Manage sources (top right button on NetFlow sources resource) and uncheck the check-box in NetFlow and CBQoS columns for that node.

I have this issue as well, but when I go to Manage Sources, only those selected, or with NetFlow data received, are showing so nothing to uncheck.
NTA appears to have gathered ALL devices from NPM, but I only want to see routers in NTA?
Please help.

Fixed my own problem..
Within NetFlow Sources, I selected ALL and removed them all, then changed the drop-down to show Only those with flow data in the last 15 mins and selected them.
Working perfectly again.
