Common TCP/IP identification section

The Common TCP/IP identification section is present in every SMF Type 119 record. This section is to identify the system and the TCP/IP stack or other address space responsible for producing the record. Table 1 provides a layout of this section. If an SMF record provides different values for the fields than those described in the layout, the values? will be documented in the description of that SMF record.

61(X'3D') SMF119TI_RecordID 1 Binary For the following SMF 119 records, this value is used to correlate several physical records which contain one logical set of information:
  • TCP/IP profile event record (subtype 4)
  • TN3270E Telnet server profile event record (subtype 24)
  • VTAM 3270 Intrusion Detection Services event record (subtype 81)
See the descriptions of these records for an explanation of this field.

For other SMF 119 records, see the description of the specific record to determine if it sets a value in this field.
