1. Re: Netdisco and Aruba Controllers (Mackie, Paul)
--- Begin Message ---
Hi,
At risk of thread-hijacking, but on the topic of Aruba WLAN.... does anyone
know why Aruba Instant AP's do not show connected devices or SSID information
(even on Virtual Controllers), but physical Aruba controllers show all info for
connected AP's and their clients. I can see this info is readily available for
IAP's via SNMP.
Is this to do with the discovery logic, or do we need updated MIB's from the
vendor? Anything I can do to push this forwards please?
Best regards,

Hey, just an update on this, I did manage to get it working developing a custom
SSH Arpnip for Aruba Controllers
Ive put it here, can be included in future release

For starters, the standard MIB for ARP tables is ancient and insufficient for
todays technology, it's just a flat list and knows nothing about VRFs, multiple
IP stacks, independent VMs inside your fancy new firewall etc. It's pretty
useless except for primitive devices.
So then every vendor has it quirks. Maybe Aruba Controllers even have a special
MIB for it, I don't know if anybody checked.
But SSH is the most reliable way to get it, and it's also pretty easy to
implement in a few lines of code.

I wouldn't say Cisco is much better, if you look closely you'll find that six
of the SSHCollector modules are for various Cisco product lines
:) It's just the most popular brand so many people have bashed their head
against it already.
Cheers
Christian
