    777 Reserved Char(6) Reserved for future use
    783 Suspected Packet Char(1002)1

A variable length field which can contain up to the first 1000 bytes of the IP packet associated with the detected event. This field contains binary data and should be treated as if it has a CCSID of 65535.

Start of changeWhen Probe Type Identifier (offset 745) is 'TR-SSL', this field contains a blank padded character string that indicates error information for the failing handshake. The first 2 bytes of this field contain the length of the error information. Following the length is a 6-byte character string that represents the processing location that detected the failed handshake. Following the 6-byte string is a 40-byte character string that indicates the error code that is returned on the failing handshake.End of change

1
This is a variable length field. The first 2 bytes contain the length of the suspected packet information.
