had you seen NetFlow data before you reinstalled NTA?
Please try this steps to troubleshoot:
1. Use WireShark at NTA box to confirm that NetFlow data exported to that machine
2. Check ports on which NTA listen for data: Admin->NTA Settings->NetFlow Collector Services. Default port for Cisco devices in 2055, for some other 9995. You can specify several ports for collector delimiting them by commas (e.g 2055,9995)
3. Under Admin->NTA Settings->Global settings check options:
Enable automatic addition of NetFlow sources
Allow monitoring of flows from unmanaged interfaces.
If that won't help you to track the problem, please open ticket for Support at http://www.solarwinds.com/support/
Thanks for your reply!
I turn off my windows firewall and restart server and now it's Ok. NTA receive data from cisco device.
