Thanks, i will try this really appreciate

A question - whats the real reason some of this data cant be gotten out of snmp 
and it needs ssh just to get arps?

Is it some limitations of the aruba product on snmp?

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
