1.7 Versioning and Capability Negotiation

None of the Microsoft RADIUS VSAs described in this document affects the versioning or capability negotiation of the protocols they are transported over. Some of the Microsoft RADIUS VSAs described in this document might not be recognized by a particular type or model of NAS - the behavior of a RADIUS client encountering unknown attributes is described in [RFC5080] section 2.5.

See the individual VSAs documented in section 2.2 for information about version fields, if any, that are used in each VSA.
