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 (warning).

Main body: "wlan ssid-profile" definition

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
(warning)ip ... # IP address of the preliminary OpenRoaming ANP-side proxy of eduroam OT
port 1812
acctport 1813
(warning)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.
rfc5997 auth-only
service-type-framed-user 1x

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

wlan cert-assignment-profile
pki-cert-assign application radsec cert-type ClientCert certname RADIUS-TLS-Cert # "RADIUS-TLS-Cert" is the friendly name given to the client certificate during upload
pki-cert-assign application radsec cert-type TrustedCA certname eduPKI-Root # "eduPKI-Root" is the friendly name given to the Trusted CA certificate during upload
