Real-time network monitoring TCP/IP NMI

Table 1 lists the updates to the Communications Server real-time TCP/IP management interface (NMI).

Table 1. Summary of new Communications Server real-time TCP/IP NMI
NMI Request/response Rel. Description Reason for change
Real-time packet and data trace NMI (SYSTCPDA) PTHDR_T packet trace header V2R1 A #pragma pack() directive was added to EZBYPTHH, the C header file that defines the packet trace header. This directive ensures that the structure mappings will not be padded. Release update
PTHDR_T packet trace header V2R1 The following changes were made for SMC-R packets:
  • New SMC trace section was added to the packet trace header for SMC-R packets.
  • New PTHIdSmc constant was added for SMC-R packets. This value sets in the CTEFMTID field of the trace record.
 Shared Memory Communications over Remote Direct Memory Access
PTHDR_T packet trace header V1R13 The following two new types are added for Pth_devty to indicate IPv4 and IPv6 IQDX interfaces:
  • Pth_IQDX
  • Pth_IQDX6
 HiperSockets optimization for intraensemble data networks
PTHDR_T packet trace header V1R13 A new Pth_IQDX field is added to indicate a packet was received over an IQDX interface. HiperSockets optimization for intraensemble data networks
PTHDR_T packet trace header V1R12 A new Pth_DtState field is added. It applies only to the new start and end data trace records. Data trace records for socket data flow start and end
A new Pth_NxtHopAddr field is added. It provides the next hop interface IP address for the packet. Packet trace filtering for encapsulated packets
Real-time SMF data NMI (SYSTCPSM) N/A V2R1 A new FTP SMF 119 record with subtype 71. NMI and SMF enhancements for TCP/IP applications
FTP server transfer initialization record V2R1
  • A new value, SMF119FT_FxProtoLevelTV1_2, might be returned in SMF119FT_FSProtoLevel to indicate that the SSL protocol is TLSV1.2.
  • A new value, SMF119FT_FxCipher4X, might be returned in SMF119FT_FSCipher to indicate that the cipher can be represented only in 4 bytes. The four-byte cipher can be obtained from SMF119FT_FSCipher4.
  • A new field, SMF119FT_FSCipher4, is returned to indicate the four-byte cipher value in use.
 AT-TLS support for TLS v1.2 and related features
FTP server session record V2R1
  • A new value, SMF119FT_FxProtoLevelTV1_2, might be returned in SMF119FT_FSNProtoLevel to indicate that the SSL protocol is TLSV1.2.
  • A new value, SMF119FT_FxCipher4X, might be returned in SMF119FT_FSNCipher to indicate that the cipher can be represented only in 4 bytes. The four-byte cipher can be obtained from SMF119FT_FSNCipher4.
  • A new field, SMF119FT_FSNCipher4, is returned to indicate the four-byte cipher value in use.
 AT-TLS support for TLS v1.2 and related features
FTP client transfer initialization record V2R1
  • A new value, SMF119FT_FxProtoLevelTV1_2, might be returned in SMF119FT_FCProtoLevel to indicate that the SSL protocol is TLSV1.2.
  • A new value, SMF119FT_FxCipher4X, might be returned in SMF119FT_FCCipher to indicate that the cipher can be represented only in 4 bytes. The four-byte cipher can be obtained from SMF119FT_FCCipher4.
  • A new field, SMF119FT_FCCipher4, is returned to indicate the four-byte cipher value in use.
AT-TLS support for TLS v1.2 and related features
Real-time SMF data NMI (SYSTCPSM) FTP client login failure record V2R1
  • A new value, SMF119FT_FxProtoLevelTV1_2, might be returned in SMF119FT_FCLProtoLevel to indicate that the SSL protocol is TLSV1.2.
  • A new value, SMF119FT_FxCipher4X, might be returned in SMF119FT_FCLCipher to indicate that the cipher can only be represented in 4 bytes. The four-byte cipher can be obtained from SMF119FT_FCLCipher4.
  • A new field, SMF119FT_FCLCipher4, is returned to indicate the four byte cipher value in use.

FTP client session record V2R1
  • A new value, SMF119FT_FxProtoLevelTV1_2, might be returned in SMF119FT_FCNProtoLevel to indicate that the SSL protocol is TLSV1.2.
  • A new value, SMF119FT_FxCipher4X, might be returned in SMF119FT_FCNCipher to indicate that the cipher can only be represented in 4 bytes. The four-byte cipher can be obtained from SMF119FT_FCNCipher4.
  • A new field, SMF119FT_FCNCipher4, is returned to indicate the four-byte cipher value in use.
 AT-TLS support for TLS v1.2 and related features
N/A V1R12 Provides new CSSMTP SMF 119 records with subtypes 48-52. Management data for CSSMTP
V1R12 Provides new DVIPA SMF 119 records with subtypes 32-37. SMF event records for sysplex events
TMI copy buffer interfaces (EZBTMIC1, EZBTMIC4, and TMI_Copybuffer()) N/A V1R13 An application no longer needs to be APF authorized to invoke the interface. Instead, for applications that are not APF-authorized, the security product profile must be defined for the real-time service interface and the user ID that is associated with the application must be permitted for READ access to the profile. Simplified authorization requirements for real-time TCP/IP network monitoring NMI
