WLC & Netflow: No interfaces under NTA?

hi k_bolt, 

good day!

I think this is better work with your device vendor and so with SW support. I strongly recommend creating a ticket to SW support for them to further check if SW NTA is really receiving a netflow data from your device. 

be prepare for a packet capture for easy identification. 

here couple of points. 

1. cisco 5520 is not supported

2. possible configuration issue, (incase that cisco 5520 do support netflow -- better check with device vendor)

netflow config compose of 3 parts, record, exporter and monitor. you might be sending netflow data (exporter and record) to SW NTA. but you haven't applied monitor to the specific interface or vice versa. 

for the bandwidth utilization, that's SNMP data(NPM),  You might want to check the SNMP being received from the device.  My experience with this one is the SNMP data being send is always the same, since it's a computation, it always shows as 0%. You can use the SNMPwalk to counter check and verify the OIDs.

Thank you Don. My issue isn't with the bandwidth utilization really. It's the fact that under NTA, the WLC is being shown as receiving Netflow traffic but the graphs don't show any data. Additionally, the WLC's interfaces are discovered under NPM (so i believe SNMP is working) BUT they aren't showing up under NTA. See the first screenshot where the Interfaces column says 0.
