The property specifies a time Time_Exceeded exceeded message, which is generated by a gateway to inform the source of a datagram that the datagram has been discarded due to the time to live property reaching zero. A time exceeded message may also be sent by a host if it fails to reassemble a fragmented Time_Exceeded 0..1 ICMPv4TimeExceededType datagram within its time limit. See for more information. Only one of the Destination_Unreachable, and Source_Quench, Redirect_Message properties can be populated. Time_Exceeded ICMPv4ErrorMessageContentType Class The specifies properties common to all types of ICMPv4 error messages. ICMPv4ErrorMessageContentType The property table of the class is given in Table 354. ICMPv4ErrorMessageContentType . Properties of the class ICMPv4ErrorMessageContentType Name Type Multiplicity Description The property specifies the IP header from the original IP_Header IP_Header 0..1 IPv4HeaderType datagram. The property specifies the first 8 bytes of cyboxCommon: First_Eight_Bytes First_Eight_Bytes 0..1 the original datagram's data. HexBinaryObjectPropertyType ICMPv4DestinationUnreachableType Class The class specifies the Destination Unreachable error message; ICMP class=3. The UML diagram ICMPv4DestinationUnreachableType corresponding to the class is shown in Figure 39. ICMPv4DestinationUnreachableType
Time_Exceeded ICMPv4TimeExceededType 0..1 The Time_Exceeded property specifies a time exceeded message, which is generated by a gateway to inform the source of a datagram that the datagram has been discarded due to the time to live property reaching zero. A time exceeded message may also be sent by a host if it fails to reassemble a fragmented datagram within its time limit. See for more information. Only one of the Destination_Unreachable, Source_Quench, Redirect_Message and Time_Exceeded properties can be populated. ICMPv4ErrorMessageContentType Class The ICMPv4ErrorMessageContentType specifies properties common to all types of ICMPv4 error messages. The property table of the ICMPv4ErrorMessageContentType class is given in Table 354. . Properties of the ICMPv4ErrorMessageContentType class Name Type Multiplicity Description IP_Header IPv4HeaderType 0..1 The IP_Header property specifies the IP header from the original datagram. First_Eight_Bytes cyboxCommon: HexBinaryObjectPropertyType 0..1 The First_Eight_Bytes property specifies the first 8 bytes of the original datagram's data. ICMPv4DestinationUnreachableType Class The ICMPv4DestinationUnreachableType class specifies the Destination Unreachable error message; ICMP class=3. The UML diagram corresponding to the ICMPv4DestinationUnreachableType class is shown in Figure 39.
