ArubaOS OpenRoaming configuration snippets

This configuration was tested on ArubaOS 8.7.1.1 (Vela build). Configuration of OpenRoaming (and Passpoint in general) is not possible via the UI, one needs to resort to CLI mode. The total configuration consists of multiple building blocks, each of which has its own section below. Much of it is copy&paste - the bits to adapt are marked with .

Uplink to authentication server: "auth-server"

The uplink can be realised over "good old" RADIUS/UDP, but then a shared secret and static IP address need to be negotiated with eduroam OT. Or, as a holder of a eduPKI RADIUS/TLS certificate, the connection can be established over RADIUS/TLS ("RadSec"). Pick one of the two variants below.

RADIUS/UDP

wlan auth-server OR_Proxy_eduroamOT
  ip ...                                                      # IP address of the preliminary OpenRoaming ANP-side proxy of eduroam OT
  port 1812
  acctport 1813
  key ...                                                     # your shared secret for the preliminary OpenRoaming ANP-side proxy of eduroam OT
  service-type-framed-user 1x

RADIUS/TLS

wlan auth-server OR_Proxy_eduroamOT
  radsec
  ip openroaming-ap.eduroam.org                                 # this is the real hostname
  port 1812                                                     # these don't matter, it is an ArubaOS artifact. The port used is TCP/2083.
  acctport 1813                                                 # these don't matter, it is an ArubaOS artifact. The port used is TCP/2083.

# the certificates themselves need to be uploaded in the web interface (Maintenance -> Certificates -> Upload -> Client/Trusted CA)
