I am trying to get NAT to receive data from a Dell switch. I have the switch sending sflow data to the IP of NTA and port configured in NTA. The switch shows all messages are dropped on this IP:port. I do not see any activity in NTA Flow Sources or CBQoS management, All messages are Last received: Never Received. Is this a supported data transfer for NTA? On the NPM/NTA server, netstat does not show a listening port for NTA, but does for NPM(80). Also telnet to the IP:<NTA Port>, I get Connection refused. telnet to IP:<NPM Port, ie:80> shows a valid listener.

Did you follow the configuration on this KB article and is your FW blocking port 2055. You can also do a Wireshark to make sure the flows are coming in.
Thanks for your reply. I have reviewed these articles, unfortunately my Dell switch uses different commands for setting up sflow. I believe I have sflow configured correctly, except for the agent-addr value that is required in the sflow command. Syntax is: sflow collector <ip addr> agent-addr <ip addr> <port>. I have not found any good info on what the agent-addr ip should be. This seems to be the only difference between the articles mentioned above and the instructions I have used. For anyone interested, I am using this link: https://www.dell.com/support/article/en-us/how11008/how-to-set-up-sflow-on-dell-networking-force10-s...
