Purview Integration Wireless Controller 9.21

[Michael_Kirchne]

Hi community,

has anyone integrated the wireless solution V 9.21 into Purview? I get the TopN Mirror up and running but I don't get netflow packets.

Netflow is configured in the section "VNS->Global->NetflowMirrorN"
There I configured the Mgmt IP of my Purview instance and choose esa1 as my L2 Mirror Port.

Any idea?

Best Regards
Michael

Hey guys, I also prepare my WLAN infrastructure for Purview and I'd need your input.

I've a single SSID/BYOD/NAC deployment with most of my APs in the office but also some in remote/home offices.

I'm not sure what the correct way is to enable Purview data collection....
Should/could I globaly enable it on the SSID but disable it for the role home office (bridge@AP).
It would make no sense to mirror all traffic back via the slow WAN link to the Purview engine.

Or should I leave WLAN service mirror disabled and enable it only on the role level (the bridge@EWC & routed roles).

What is the difference... on the WLAN service the selection is "enable both directions" but in the role the option is only "enabled".
Does it give the same information back to Purview ?

Thanks,
Ron

Hi Michael,

The 9.21 Wireless controller is sending out Netflow packets... However, it is sending it on Port 2095. NS/Purview6.2 does not listen on that port and therefore does not display any Netflow data. You need Purview6.3 in order to receive and analyze the records.

Therefore you need a minimum base of NetSight/Purview 6.3 in order for the integration to work correctly.

Hi Paulo,

thanks for the reply. I'm running NetSight 6.2. But what has the NetSight Version to do whether the wireless controller sends out netflow packets or not? In my opinion this is more WIreless controller related.

Hi Michael,

What version of NMS are you running? You will require Netsight 6.3 as well. NetSight 6.3 is schedule for Early Access at the end-of-the-month.
