Discovery of Wireless Access Controller - CI Classes

[David77]

When we run Discovery Patterns against our Wireless Access Controllers and Access Points, is is accurate to say that the following CI Classes will be used:

---device ------------- : --- CI Class used --------

Wireless Controllers: IP Routers

Wireless Access Points: Wireless Access Point

Secondly, how does Discovery of WAP work, generally?  Does it go to the Controller, and then collect the information about all Access Points connected to it, or does Discovery have to physically be able to reach out to all the Controllers *AND* each Access Point?

Thanks!!

We were able to discover all Wireless Access Points using the recently released "CMDB CI Model" and "Discovery and Service Mapping Patterns" plugins. The ServiceNow version we are using is Paris.

We scan the Wireless Controllers and it creates all the WAP CI from there. It uses the Network Switch Pattern.

Not sure if this answer your question.

Sha_pan, thanks!   One observation we've had is that the number of Wireless Access Points Discovered does not match (is lower than) the number our Network Team is saying our connected to the controllers. 

We're not seeing errors in our Disco logs for the controllers, but yet not all WAPs are being found. 

Have you experienced that issue at your site?  We're on Orlando, and working on Paris.   Thanks!

That only happened to us on 2 specific locations because they are using a different model for the Wireless Controller. So I had to change the classifier of that Model into Standard Network Switch on the SNMP OID Classification table as the default was Standard Network Router 

Not sure if that would help but we our Network Engineers currently don't maintain any inventory lists of all WAP so it's difficult to track if any CIs are missing. They are all relying on CMDB. And so far no one are complaining. 🙂

We were able to resolve the mismatch on counts ... one of our WAP Controllers was not being Discovered. 
Thanks everyone!

Hi All,

After the WAPs are discovered, does it show the IP address mapped to the AP as well? I am not seeing the IP address mapped and hence asking the question.
