Dell NativeEdge: So überprüfen Sie die Konnektivität zum Dell Public Rendezvous-Server

Der Dell RV Server ist eine öffentlich zugängliche, sichere Website, die an der Übertragung von Gutscheinen beteiligt ist. Ein NativeEdge-Endpunkt sucht beim Onboarding nach dem RV-Server, führt Handshakes durch und schließt den Onboarding-Prozess ab.

Empfehlungen zur Fehlerbehebung:

• Angehängte Concise Binary Object Representation (CBOR) herunterladen msg30_pkb.zip Datei aus den Anhängen dieses Artikels
• Extrahieren Sie die msg30.cbor Datei auf einem System, das über einen Internetzugang verfügt und CURL
• Führen Sie den folgenden Befehl aus:

Orchestrator online (Internetzugang)

curl -v -H "Content-Type: application/cbor" -H "User-Agent: fdo" --data-binary "@msg30.cbor" https://rv.dell.com/fdo/101/msg/30

Erwartete Ausgabe:

• Host, auf dem ausgeführt wird CURL muss in der Lage sein, den RV-Server aufzulösen (über einen DHCP-Eintrag oder lokal).

• Das System sendet 22 Byte binäre CBOR-Daten von msg30.cbor.
• Dies ist die Meldung 30 des FIDO Device Onboard (FDO)-Protokolls: TO1.HelloRendezvous o. ä. im Onboardingablauf

HTTPS-Antwort

• Authorization: Inhaber...: Der Server gibt ein Bearertoken aus – dies ist die FDO-Meldung 31, TO1.HelloRendezvousAck
• Meldungstyp: 31: Bestätigt den Meldungstyp im FDO-Austausch

Weitere Informationen zu den Meldungen HelloRV (Typ 30) und HelloRVAck (Typ 31) finden Sie in der FDO-Spezifikation: https://fidoalliance.org/specs/FDO/FIDO-Device-Onboard-PS-v1.1-20220419/FIDO-Device-Onboard-PS-v1.1-20220419.html#TO1HelloRV
