Hi all, first of all, thank you for your help so far! I do have another question regarding EAP-TTLS. According to eap ttls | FreeRADIUS Documentation (networkradius.com)<https://networkradius.com/doc/3.0.10/raddb/mods-available/eap/ttls.html> and RFC5281 (RFC 5281: Extensible Authentication Protocol Tunneled Transport Layer Security Authenticated Protocol Version 0 (EAP-TTLSv0) (rfc-editor.org)<https://www.rfc-editor.org/rfc/rfc5281.html#page-15>), Diameter is being used in this protocol to allow the usage of AVPs. But is there another reason why EAP-TTLS uses Diameter packages? I am asking, since I checked some PEAP packages with Wireshark and these packages, while not using Diameter, still have AVPs incorporated in them. I also can not find any sources that state why Diameter was specifically chosen for EAP-TTLS. Was there another advantage that Diameter offers in the case of EAP-TTLS? I.e. client roaming capabilities, failover, etc.? Kind regards, Calvin
