Hope someone can help me solve this one as it's driving me crazy!
I've got an HP Procurve 2610-48 switch which Netflow Traffic Analyser doesn't seem to want to receive data from. Once I've configured the device to send the Netflow data, Orion reports that it's receiving a data stream from an unmanaged device with an IP which does indeed match the IP of the device. However, once I add the device to Orion and tell Netflow Traffic Analyser to collect data from it, the stream appears to stop; the device is listed in italics and the 'last data received' date says 'never'.
The error saying that the data stream would be discarded sometimes says that I need to add interface #1073741823 in order to process the data stream, but this interface doesn't exist. I don't always get this though (I've been through the whole configuring - managing - giving up - configuring cycle about 10 times and have changed IP addresses several times as well).
I added several other switches of the same model at the same time and they're all fine so I need to work out what's different about this one. Any suggestions?
Have you looked at a sniffer trace of the incomming data? If not, you can use WireShark to do that. It is a free tool located here: http://www.wireshark.org/
If you do see that Flows are coming to the port (default 2055), then you can save the file and attach it to this thread in Thwack and I'll take a look at it, just to verify that you have traffic that our collector can recognize.
