Changing from MirrorN to IPFIX in ExtremeWireless

Changing from MirrorN to IPFIX in ExtremeWireless

I have an existing integration of EWC and Purview, however I went to use it today and it seems to have stopped working after I upgraded the analytics appliances to 8.0.2.42 a month ago. Some quick debugging hinted that while Netflix and mirrorN traffic was coming through, the appid process wasn't listening on the correct ports for some reason.

I figured it was then a good time to try and migrate to the new IPFIX-based method that doesn't need an L2 port any more. I followed https://extremeportal.force.com/ExtrArticleDetail?an=000090154 and set the Traffic Mirror L2 Port to None, and set traffic mirror to prohibited in all the VNS/Role configuration, but it's still not working. Anyone know what other configuration I need to set to make it use IPFIX?

I had some similar issues when I upgraded to 8.0.2.42. It took a couple hours with support to figure it out. It turns out that it was a certificate error. I had generated my own certificate from a CA in my environment and NMS was having none of it. By deleting the certificate and going back to the self-signed certificate, Purview was then able to connect.

I also had errors bringing up and of the legacy Java stuff. But I was getting different errors after fixing the cert. And I fixed the Java problem by updating the version of Java installed on my machine.

Correct. I wouldn't expect a reboot of Purview would help. Purview, like Console is considered a client machine and neither can connect because of an issue with the EMC server.

Yep, going from EMC 8.0.3.46 to 8.0.3.53 fixed the issue here too. I actuall upgraded the Analytics engine first, but that wasn't enough.

I also found https://extremeportal.force.com/ExtrArticleDetail?an=000081442 which notes I was wrong to disable the traffic mirror and Netflow, all I needed to do was disable the traffic mirror L2 port.

Hi James,

I have updated my appliances, EMC and Analytics, and I can confirm that the latest update, 8.0.3.53, I am no longer seeing this issue.
