Wireless Access Point (WAP) Discovery?

Vini · ‎09-21-2020

Hi All,

We are trying to discover Wireless Access Points(WAP's) and Controllers using SNMP Community String.

But the system is not discovering any WAP devices. Is it feasible to discover WAP's directly from Service Now Discovery or we need to do any customization's for discovering those?

Hi All,

Finally I was able to discover WAP's on Orlando version.

Implementation Steps#

1. Made the "Wireless LAN Controller" classification to false.

2. Made the OID "1.3.6.1.4.1.9.1.2170" with classifier "Standard Network Router" to false

3. Created new OID "1.3.6.1.4.1.9.1.2170" with classifier "Standard Network Switch" and made it true.

4. Ran the discovery but discovery failed with "Running pre sensor script- WAPs - Pre failed due to: TypeError: Cannot convert null to an object.."

5. Made changes to the "pre sensor script- WAPs - Pre" FROM: 06a71b1367e4130051c9027e2685ef1e TO: global - As per "KB0827636" article I have changed "Accessible from" to "All application scopes" - added "global." in the "WAPs - Pre" Pre Post Sensor script in front of occurrence of this "PatternJSUtil" var makeAndModel = global.MakeAndModelJS.fromNames(manufacturer, model, 'hardware'); if (!global.PatternJSUtil.nil(makeAndModel.getManufacturerSysID())) currentItem.values.manufacturer = makeAndModel.getManufacturerSysID(); if (!global.PatternJSUtil.nil(makeAndModel.getModelNameSysID())) currentItem.values.model_id = makeAndModel.getModelNameSysID(); <

6. ran the discovery and now it is working successfully.

Note# 1. WAP’s can be discoverable on Paris version because Switch pattern has extension section of WAP.

Hope this helps!!!

Thanks & Regards,

Vinil.

There is no out of the box mechanism for discovering wireless access points (WAP). However, if the Access Points have a controller which supports and can be configured with SNMP, they can be discovered.

Use below article for the steps to achieve this.

if they are Cisco WAPs you can check out

Hi,

If you have updated the patterns and if you are using pattern based discovery then Yes that is possible out of the box. Network Switch pattern has a extension section which is used to discover the WAPs OOB.

So please check if you have those patterns for Discovery nd Service Mapping plugin activated and updated from Store.

Thanks,

Hi Vinil,

Did you get a solution to your problem ?

By any chance, did you create custom probes/sensors ?
