SMF type 120, subtype 11, version 2 and version 3 record mapping
The SMF data in the type 120, subtype 11, version 2 and version 3 record contains a header followed by five triplets that are used to locate the data that is associated with that triplet. A triplet has three 4-byte fields, which stand for the offset, the length, and the count.
The following table lists the data mapping of the SMF type 120, subtype 11, version 2 and version
