I have configured sflow on a Brocade switch but I can see only ingress traffic on the Solarwinds NTA. egress traffic is not displayed.
has anyone encountered this problem?
I would start reviewing the Brocade configuration, here something to help Brocade (Foundry) sFlow configuration or Example Config - Brocade (Foundry) sFlow Configuration
Assuming everything is ok I would troubleshoot using Wireshark first, here something to help NTA - Netflow v5 Wireshark packet capture, How to troubleshoot NetFlow using Wireshark - Video, Breaking down sFlow packet in Wireshark.
If it doesn't work, lets us know. Paste the configuration and the Wireshark results here so we can take a look together.
Indeed, netflow is configured on the brocade switch. Also, I can see packets on the wireshark using sflow analyze.
However, I'm still seeing only ingress on the NTA comming from this node, no egress traffic. It's kinda weird with those brocade switches, I had no issues with Cisco devices.

Any luck with this??
NTA received a packet indicating that NetFlow data export on device 10.121.133.68 might not be enabled. If you cannot see NetFlow data from the device in NTA, make sure the device is configured to export NetFlow. » Learn more.
