Re: [Netdisco] Aruba Instant AP Serial Number Help

[Mackie, P. <Pau...@ge...>]

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.

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.

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
