Netflow data not showing up in solarwinds

cyberchild over 10 years ago

We just brought the solarwinds and I am very new to this
product. I am setting up the Netflow
from the cisco switch to Solarwinds Netflow module. I am see netflow information on my switch but NOT seeing any data on solarwinds. Does anyone
guide me to how to troubleshoot this issue?

I setup netflow on my switch on one of my vlan and want to
monitor netflow in solarwinds.

Please post the NetFlow config from your switch.

That looks right, although I'm not sure how NTA handles the data from the "ip flow ingress layer2-switched" command. Things to check:
1) Do you have data in your flow cache ("show ip cache flow")?
2) Does "show ip flow export" look like you are sending flow exports?
3) If you run a packet capture for UDP port 2055 on the NTA box, are you receiving flows?
