Issue/Introduction

Spectrum performance issues were seen when wireless LAN controllers were configured in dual mode. 

Cause

The wireless access point (AP) models were switching between the primary and secondary wireless LAN Controllers on every poll cycle. This was causing the CORBA Notification threads to back up with WLC_Contains relation changes. 

Environment

Release : 20.2

Component : Spectrum Core / SpectroSERVER

Resolution

This issue is resolved with NetOps 20.2.3. Only actively connected Aruba access points will be modeled and associated to the primary controller. Switching is avoided until fail over happens.
