If there is only one node in the cisco wlan-cluster all looks good, no duplicates regarding the access point's=antennas

 

But as soon there is a second node in the cluster, the node that get's updated with a configuration poll shows all the AP's and duplicates:
 

and the second node has no AP's anymore, except for two AP's which are operational down, if we now
run a config poll on this node it will get all AP's with duplicates, and the other one will have no AP's anymore.
Do we have a config in NNMI to change this behaviour, or is it simply a BUG

    Hallo Gero,

    I was able to check this today (.1.3.6.1.4.1.9.1.2860, ciscoCatalyst 9800-L-C, Version 17.9.4a) and I can confirm the "switch" of the Access Points when running config poll. Currently I discuss with the customer to add only one WLC using the HA IP address to NNM and to monitor HA state via .1.3.6.1.4.1.9.9.843.1.3.4 (cLHaPeerHotStandbyEvent) using Custom Poller.

    I am interested in how the new deep monitoring of Cisco WLC is impacted by adding both or only one WLC (using the HA IP address) in NNM.

    Best regards
