1. Trying to fetch arp entries from ArubaOSCX, again (Jethro Binks)
--- Begin Message ---
Hey all,
Given:
*
I can't yet upgrade to latest ND with the new magic python stuff
(https://github.com/netdisco/netdisco/issues/1367)
*
One cannot retrieve Arp entries from Aruba OSCX over SNMP yet
(https://github.com/netdisco/snmp-info/issues/452)
I thought I'd have another go at the SSHCollector; starting with the Aruba one
(which is for the AOS wireless controllers) and then modifying for OSCX,
resulting in a new App/Netdisco/SSHCollector/Platform/ArubaCX.pm.
Here's my deployment stanza:
- tag: ssharubacx1
driver: cli
platform: ArubaCX
action: arpnip::nodes
only: ipaddress
username: username
password: password
ssh_master_opts:
- "-T"
- "-o"
- "StrictHostKeyChecking=no"
But no matter what I try, when I run the arpnip:
netdisco-do -D arpnip -d ipaddress
It never seems to actually try to use the CLI module:

[39947] 2025-08-21 19:25:47 debug snmp reader cache warm: [ipaddress]
What am I missing here?
Meanwhile, is there a way I can directly call ArubaCX.pm with a bit of a
wrapper, outwith Netdisco, to test it actually works?
While one day I might get this working, I consider it a bit of a hack, and the
real solution here is the lack of SNMP::Info support for ipNetToPhysicalTable
as discussed in #452 and really I'd love to see some progress with that ...
Jethro.
