Prime 3.5 does not show APs and Clients of WLC9800. Inventory Status shows "Partial Collection Failure".
On the WLC I noticed that Telemetry connection is stuck in "Connecting".
Does someone know how to fix this?
As far as I know there is an additional update available.
The following versions are installed:
PI 3.5 Update 02
Prime Infrastructure 3.5 Device Pack 3
Cisco IOS XE Software, Version 16.11.01b
I suggest you upgrade to Update 03, because it fixes a lot of critical security issues:
But otherwise the version looks fine and I think the 9800 should be supported by DP3. I suggest you open a TAC. On the other hand, the 9800 is probably newer than 3.5 and could not be fully implemented.
Based on, for example, this bug: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvj68855 it should show the APs on a 9800 WLC in PI 3.5, although it is buggy.
I haven't checked all the known issues, you might find something here: https://bst.cloudapps.cisco.com/bugsearch/search?kw=infrastructure%209800&pf=prdNm&sb=anfr
It seems 3.6 is of no real help either: https://community.cisco.com/t5/wireless-security-and-network/no-aps-seen-in-cisco-prime-infrastructure-3-6-with-wlc-9800-cl/m-p/3874275
