Vendor-Specific-Application-Id AVP

The Vendor-Specific-Application-Id AVP (AVP Code 260) is of type Grouped. This AVP indicates that the SBC supports an application. This AVP includes the following AVPs:

  • Auth-Application-Id—This unsigned32 AVP uses code 258. It indicates support of the Authentication and Authorization portion of an application, and is required in all accounting messages.
  • Acct-Application-Id—This unsigned32 AVP uses code 259. It indicates support of the Accounting portion of an application, and is required in all accounting messages.
  • Vendor-Id AVP—This unsigned32 AVP uses code 266. It contains the code assigned to the vendor responsible for this Diameter application.

The Vendor-Specific-Application-Id AVP must have only one instance of both or either Auth-Application-Id or Acct-Application-Id AVP to avoid being rejected. The Vendor-Id may have a value of zero, which indicates that it should be ignored.
