GM:

 

When trying to scan WAP connected to a Cisco Systems, Inc. Catalyst 9800 Series WC we get no results, i.e. it only brings the info related to the WC and it does not pull any of the WIP data along with it. When checking the Discovery logs there are no errors, no indication as to why we are not able to scan the WIP.

 

We are discovering WAPs connected to switches, however when it comes to WAPs connected to this Cisco router, we cannot discover them. 

 

has anyone faced the same situation?

Hi all, 

I faced this issue as well, where Cisco WLC is detected as IP Router, and therefore are not discovered correctly, leading to the WAPs are not discovered.

 

More details on my case:

  • Cisco Systems C9800
  • Cisco IOS Software [Dublin], C9800 Software (C9800_IOSXE-K9), Version 17.12.3, RELEASE SOFTWARE (fc7)

 

The Ecc Queue shows:

At the end I managed to solved it by doing the following:

  1. Check the OIDs from the Payload in the Ecc queue

  2. With help of AI, and hints from @Jeric_ Flores2 , I created following OID entries
    1. 1.3.6.1.2.1.1.1 
      HSU_1-1769488474540.png

       

    2. 1.3.6.1.4.1.9.1.2861 (this is suggested by AI)

    3. Both are entered
      1. Table: IT Switch
      2. Classifier: Standard Network Switch
  3. Restart the Discovery again
    • Check the Ecc Queue
      HSU_4-1769487345457.png
      • It shows Network Switch pattern has been triggered
    • Check the WLC CI 
      • It is now saved in the cmdb_ci_ip_switch
      • All the WAPs are also discovered as CI and connected

 

Remarks: I don't need to upload any MIB from the CISCO.
