i am using PRTG 18.104.22.16881. We have about 40 ASA's each with a active NetFlow export to a PRTG Server. The ASA's use Version 9.2.3 The Server is in an other Network Segment.
2 of the NetFlow Sensor not reciving any data. i check the config for the asa that work fine and can't find no differens to that not working.
I use the NetFlow Tester and each Outpout is the same. With the Tester i recive NetFlow Packets it look ever like Unassigned Flows (ID:#) 256 261 263
Templatees received (ID) 285 284 283 282 281 280 279 278 277 276 275 274 273 272
Decoded Flows -empty-
Thats for all ASA's the same.
I also deltete the Sensors from the non wotrking and create it new but no diffrence.
What can i do next to come up with this? thanks Karsten
