I've added the Arista switch and Cisco WLC sysOIDs to the DeviceTypes.xml file in the Switches and WirelessControllers sections respectiviely. The Switches section has sysServicesOverride set to 'true' and the WirelessController section has sysServicesOverride set to 'false'.
Cause
Symptom: Device type changes in the data aggregator are not always reflected in NetOps Portal; DE508178, fixed in 23.3.5
Resolution
Upgrade to 23.3.5 or higher
Additional Information
Resolution: With this fix, device type changes in the data aggregator are now synchronized and reflected in NetOps Portal.(23.3.5, DE508178, 32759736)
