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.

Hi @Akshatha

I hope you musy have tried reply posted by Ashutosh.

================================

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.

Hi Rahul,

I did read the Ashutosh's reply to this post. I was confused since I am very new to service now.

By any chance are you and Ashutosh referring to highlighted ITOM pattern in attached .png ?

If not, Can I get the Plugin ID of "Discovery and service mapping pattern" ? (Is it free or paid ? - Out of curiosity).

Kind Regards,

Akshatha

Hello Rahul,

Any help is Highly Appreciated!!

Thanks,

Akshatha

(1) on PDI and Non Production Instance ITOM -Discovery is Free. Its Paid Once You use it on Production and You need to procure Its Subscription.

(2) Do you have Discovery Plugin enabled on your Instance?(com.snc.discovery)?

What is referred in previous thread was - Once you have discovery enabled you have 500+ pattern which are available on Instance. These Pattern is used to discover CIs and relationships creation.

A sample screenshot is here.
