assoc Application Protocol

1.3.6.1.2.1.27.2.1.3

An identification of the protocol being used for the application. For an OSI Application, this will be the Application Context. For Internet applications, OID values of the form {applTCPProtoID port} or {applUDPProtoID port} are used for TCP-based and UDP-based protocols, respectively. In either case 'port' corresponds to the primary port number being used by the protocol. The usual IANA procedures may be used to register ports for new protocols.
