 Thanks for the screenshot, Paul
I have the same view and it includes the Aruba AP Serial field but that 
unfortunately doesn't contain any info for me. I'll investigate the Hook::exec 
jobs and turn on some debugging to see if that reveals the error of my ways.
Thanks again

Hello,
 
  
 
I’m not sure, it works reliably for me on AOS-8 and AOS-10 devices. Note that 
the serial number field will remain unpopulated, you should see a new field 
called ‘Aruba AP Serial’ if you followed my approach below. You will also see 
‘Hook::exec’ jobs in the Job Queue, as this custom field is queried outside of 
the normal discovery.
 
  
 
As for how to proceed, I’m not really sure what to advise, but I would check 
those Hook::exec jobs are running first.
 
  
 

 
  
 
  
 
Best regards,
 
Paul Mackie

Paul, I have added those to my deployment.yml plus installed jq support but 
still don't get serial number info on any of the Aruba IAPs other than the 
virtual controllers. Should I purge the database or start with a fresh install 
of Netdisco?
 
  
 
My Unifi, Liebert / Vertiv, Fortinet and HP network devices all have the serial 
number column populated.
 
  
 
Thanks your time and assistance

No I did not make any changes to aruba.pm, just added the custom field.

Thank you for that, Paul
 
 
 
I have modified my deployment.yml to include your settings and am waiting for 
the results. By chance did you make modifications to your aruba.pm or is it the 
default?
 
 
 
BTW, I'm on Netdisco version 2.097002, aruba.my and aruba-instant.my are tagged 
ArubaOS 8.13.1.0_93688 if that makes a difference.
 
 
 
Thanks again for the help

Probably not the answer you are looking for, but I gave up to some extent and 
went for the custom field like shown below.  This works for all our IAP’s 
whether virtual controllers or members.
 
 
 
host_groups:
 
  aruba_access_points:
 
    - 'os:airos'
 
 
 
host_group_displaynames:
 
  aruba_access_points: 'Aruba APs'
 
 
 
custom_fields:
 
  device:
 
    - name: 'arubaserial'
 
      label: 'Aruba AP Serial'
 
      snmp_object: 'AI-AP-MIB::aiAPSerialNum'
 
      only: 'group:aruba_access_points'
 
 
 
Would be great if we could also pull all the AP info such as SSID and connected 
clients etc on Instant AP’s just like we can with real controllers. It is 
exposed by SNMP but Netdisco doesn’t see it. That’s not related to your issue 
though.

Subject: Re: [Netdisco] Aruba Instant AP Serial Number Help
 
 
 
I just tried a new aruba-instant.my and guess what - I now have a few serial 
numbers on the inventory page. They are displaying in the following format: 
 
 
 
HASH(0x000000000000) VNQ0000000 
 
 
 
[the example ^ has obfuscated information]
 
 
 
The few that now have serial number information turn out to be the IAP devices 
elected as the virtual controller for each of our Aruba Central groups.
 
 
 
Can anyone offer a configuration (either Aruba or Netdisco) for the individual 
Aruba AP315, AP365, AP375, AP567, AP615 and AP635 models to respond with their 
own serial numbers?
 
 
 
TY

I have the same problem and can't get it sorted. Have hundreds of various 
models of Aruba IAP across campus. When I SNMPwalk them from the cli, serial 
reports as undef. 
 
 
 
When I try 
 
netdisco-do show -d <IP> -e AI-AP-MIB::aiAPSerialNum 
 
it too returns undef.
 
 
 
I *believe* I modified the Aruba.pm correctly but have the same results.
 
 
 
Vertiv / Liebert UPS, HP switches and some of my Unifi Nanobeam bridges - 
Netdisco discovered those with no problem at all. 
 
 
 
I have read the earlier posts about this issue and just not making any headway. 
Understand I am only days into a Netdisco install so I have much to learn. Was 
there a resolution and I am overlooking something simple?
 
 
 
Thanks
