This attribute is an enumerated value that indicates the transport medium to use when creating a tunnel based on a protocol that can support multiple tunnel types. If the attribute is present in an Access-Request packet, the RADIUS server should read its presence as a hint; it is not required to honor that request.

The possible values for the Tunnel-Medium-Type attribute and their corresponding meanings are listed in Table 9-3.
