Discovery put my wireless access points in the wrong Table/CI Class

Hi Everyone,

In my current environment, we have noticed that WAP devices are classified as IP switches  and polled to IP Switch [cmdb_ci_ip_switch] table.

They should ideally be polled to Wireless Access Point [cmdb_ci_wap_network].

1. is changing the table from IP Switch to Wireless access points recommended.

2. If I delete the OID entry in the snmp classifications table and do a quick discovery, will it create a new entry in the SNMP Classifications table.

3. I have created a classifier for wap devices on wireless access points table, what should be the classification criteria, what trigger probes should I include here.

4. I deleted the SNMP OID which was pointing to wireless access points table (I created a classifier for WAP devices and changed the table to point to wireless access points table) and did a quick discovery, and it is discovered as IP Switch but has not created any SNMP System OID, is this expected behavior. If yes do we need to create SNMP OID in the SNMP Classifications table.

 

5. if there are no snmp OID's, on the first discovery will they be inserted in snmp OID table automatically or manually create an entry

6. modifying the class in the OOB classifier will have any impact, is it recommended
this is because the OID's are pointing to Routers and Switches table and I changed to WAP table

7. under the wap classifier, any snmp OID classification pouting to other tables like switch, router should they be changed to wap table?

Apologies, if you see some of these queries are repeated

What version of SN are you on and are you on the latest Discovery Patterns from the store?  We have included WAP discovery as part of the Network Switch pattern.

Hi Ryan,

This is the query raised against us, 

  1. WAP -> Wireless Access points

The CI are classified as IP switch after discovery rather they should be discovered as Wireless Access points

We are on Orlando Patch 7.

We are in the transition and I'm not sure if we are on the latest patterns from the store.

If that is said, we don't have to create any new classifier in the table 'discovery_classy_snmp' and 

map to table 'discovery_classy_snmp'

Please help me which store app 

Discovery and Service Mapping Patterns or CMDB CI Class Models, should I try.

Thanks & Regards,

Krishna

Hi @krishnakk 

In the latest pattern WAPs are stored in cmdb_ci_wap_network table. there is an extension section in network switch pattern which would store the wap data wap table.

 

Hi Pooja,

I do not see anything in the extension section of IP Switch pattern. 

Can you please help me withe correct path, if I missed anything here
