Can the automatic discovery/creation of Access Points (AP) in Dx NetOps Spectrum be stopped for any Wireless Lan Controller (WLC)?

Issue/Introduction

DX NetOps Spectrum supports modeling Wireless LAN Controllers (WLC) and their corresponding Access Points (AP).

Once the Access Point discovery has been launched Spectrum will poll the WLC every 5 minutes for AP modeling info.  This can cause SS performance problems in networks with many WLC and APS

How can I configure Spectrum to discover the AP every 12 hours instead of every 5 minutes?

Environment

Spectrum: Any release

Resolution

There is an attribute named enableAPDisc (attribute id 0x13340) on the WLC Application model that controls the AP discovery. 

The enableAPDisc attribute is available on the following WLC application models:

• Cisco_LWAPP_App
• Aruba_Controller_App

Setting the value to False will disable the automatic AP discovery.  Setting it back to true will trigger the discovery.  

It is recommended that you set this to False/disabled on the Cisco_LWAPP_App and Aruba_Controller_App models and you enable the WLC Scheduled AP discovery on the WLC Manager model instead.

In the Explorer view of OneClick select the WLC Manager model and click on the Information tab in the Contents window

In the Configuration section, change the "Enable Scheduled Discovery" to Yes and leave the timer at 12 hrs.

Additional Information

If you would like to stop AP discovery altogether, make sure the enableAPDisc attribute is False on all Application models and set the Enable Schedule Discovery to No on the WLC Manager model.

 

It is recommended to set the enableAPDisc attribute to False for all Cisco_LWAPP_App and Aruba_Controller_App currently in the database and setting the default value to False for future models.  Then enable the Schedule Discover on the WLC Manager.
