Must be missing something obvious here. Many people seem to be using the 5406 with RNA, but I can't get it to work. On the switch:
sflow 1 destination 10.22.70.17
sflow 1 sampling Trk1 500
Changed the port number in RNA to 6343 and verified with Wireshark that packets are coming in. Also tried the default RNA port, with that port configured on the HP. Same thing, the SNMP counter show traffic on the itnerface, but the "Sending Netflow" column never updates. If I hit "Start Flow Capture" I get an error.
5406 is fully patched, RNA freshly downloaded, firewall on PC disabled
From what you're showing, it looks like you have configured sFlow instead of NetFlow. Is this correct?
Realtime NetFlow Analyzer is only compatible with NetFlow v1 and NetFlow v5. Orion NetFlow Traffic Analyzer supports sFlow. You can try a free evaluation version to see if it does what you're looking for.
