6.10. Inband-Security-Id AVP

The Inband-Security-Id AVP (AVP Code 299) is of type Unsigned32 and is used in order to advertise support of the security portion of the application. The use of this AVP in CER and CEA messages is NOT RECOMMENDED. Instead, discovery of a Diameter entity's security capabilities can be done either through static configuration or via Diameter Peer Discovery as described in Section 5.2.

The following values are supported:

NO_INBAND_SECURITY 0

This peer does not support TLS/TCP and DTLS/SCTP. This is the default value, if the AVP is omitted.

TLS 1

This node supports TLS/TCP [RFC5246] and DTLS/SCTP [RFC6083] security.
