Table 1 lists the SNA commands that have changed behavior.
For complete information about SNA commands, refer to the z/OS V2R1.0 Communications Server: SNA Operation.
| Command | Release | Description of behavior change | Reason for change |
|---|---|---|---|
| DISPLAY EE | V2R1 | IST2346I is added to output that contains information about a remote IP address or a remote host name. | Serviceability Enhancements |
| DISPLAY EEDIAG | V1R13 | When TEST=YES and LIST=SUMMARY are specified together, messages IST2137I and IST2138I now have *NA for the hop count. Previously, IST2137I and IST2138I were displayed with the actual hop count. | Enterprise Extender firewall-friendly connectivity test |
 DISPLAY ID |
V2R1 |
If ID=rnictrle_name is specified and the 10GbE RoCE Express feature
that rnictrle_name represents is
operating in a shared RoCE environment, message IST2417I appears in
the command output to display the associated virtual
function number (VFN). |
Shared Memory Communications
over RDMA adapter (RoCE) virtualization |
| V2R1 | If the resource that is being displayed is a RNIC TRLE, a new message group (IST2361I) is generated to display information that is unique to the 10GbE RoCE Express interface. | Shared Memory Communications over Remote Direct Memory Access | |
| V2R1 | When the ID represents a high performance routing (HPR) physical unit name, IST2395I is issued if the base mode adaptive rate-based (ARB) pacing algorithm is used. | Serviceability Enhancements | |
| DISPLAY ID | V1R13 | When ID=trlename is specified for an active QDIO TRLE, messages IST2331I, IST2332 and one or more IST2333I are issued. For messages IST2331I, IST2332I, and IST2333I, a new QUEUE STATUS column now shows the current status of each read queue. | Performance improvements for Enterprise Extender traffic |
| V1R13 | The command is enhanced
in the following ways:
|
HiperSockets optimization for intraensemble data networks | |
| V1R12 | When ID=trlename is specified for an active QDIO TRLE, messages IST2331I, IST2332 and one or more IST2333I are issued. Previously message IST1918I was issued. Message IST924I is added to separate data device information. | Performance improvements for sysplex distributor connection routing | |
| V1R12 | When ID=trlename is specified for an active QDIO TRLE, message IST2337I describing the chpid type and number is issued. | z/OS Communications Server in an ensemble | |
| V1R12 | When the ID represents a high performance routing (HPR) physical unit name or line of the Enterprise Extender XCA major node (MEDIUM=HPRIP), the display output is enhanced to optionally include the additional messages IST2327I, IST2328I, IST2329I, IST2339I, IST2340I, IST2341I and IST2343I. | Enterprise Extender connection health verification | |
| DISPLAY STATS | V2R1 | When you specify TYPE=CFS,STRNAME=EZBDVIPA, entries can also be displayed for IPv6 addresses. | Sysplex-Wide Security Associations for IPv6 |
| V1R13 | When TYPE=VTAM is specified, existing message IST1227I displays the VIT size in megabytes. Message IST1227I for the status value 2 displays the VIT size. IST1227I for the status value 163 is retired. | Increased CTRACE and VIT capacity | |
| DISPLAY TOPO | V1R13 | When LIST=SUMMARY is specified and APPN routing trees were cleared, new message IST2360I displays the date and time of the last clear operation. | Improved APPN routing resilience |
| V1R12 | When ID=cpname,LIST=ALL is specified, the display output is enhanced to include additional messages. | Enhancements to topology database diagnostics | |
| V1R12 | When ORIG=orig,DEST=dest is specified, the display output is enhanced to include additional messages. | Enhancements to topology database diagnostics | |
| V1R12 | When LIST=TDUINFO is specified, the display
output is enhanced to include, in addition to information about TDUs
received, the following information:
In addition, when LIST=TDUINFO,SCOPE=ACTIVITY is specified, the display output is enhanced to include information about RSN updates. Also, when a new FORMAT operand is specified on LIST=TDUINFO, the output is displayed in an expanded format. |
Enhancements to topology database diagnostics | |
| DISPLAY TRL |
V2R1 |
If TRLE=rnictrle_name is specified and the 10GbE RoCE Express feature
that rnictrle_name represents is
operating in a shared RoCE environment, message IST2417I appears in
the command output to display the associated virtual
function number (VFN). |
Shared Memory Communications
over RDMA adapter (RoCE) virtualization |
| V2R1 | When the TRLE operand specifies a RNIC TRLE, a new message group (IST2361I) is generated to display information that is unique to the 10GbE RoCE Express interface. | Shared Memory Communications over Remote Direct Memory Access | |
| V1R13 | When TRLE=trlename is specified for an active QDIO TRLE, messages IST2331I, IST2332 and one or more IST2333I are issued. For messages IST2331I, IST2332I, and IST2333I a new QUEUE STATUS column now shows the current status of each read queue. | Performance improvements for Enterprise Extender traffic | |
| V1R13 | The command is enhanced
in the following ways:
|

| V1R12 | When TRLE=trlename is specified for an active QDIO TRLE, messages IST2331I, IST2332 and one or more IST2333I are issued. Previously message IST1918I was issued. Message IST924I is added to separate data device information. | Performance improvements for sysplex distributor connection routing | |
| V1R12 | When TRLE=trlename is specified for an active QDIO TRLE, message IST2337I describing the chpid type and number is issued. | z/OS Communications Server in an ensemble | |
| DISPLAY VTAMOPTS | V2R1 | When FORMAT=CURRENT is specified and the current IPADDR start option value is larger than 17 characters, message IST1904I is displayed instead of IST1189I. | Enterprise Extender IPv6 address configuration |
| V2R1 | When FORMAT=COMPLETE or FORMAT=MODIFIED is specified, and the IPADDR start option value is currently larger than 17 characters or was larger than 17 characters when VTAM was started, messages IST1905I, IST1906I, IST1907I, and IST1908I are displayed instead of IST1310I. | Enterprise Extender IPv6 address configuration | |
| MODIFY TRACE | V1R13 | A SIZE specification that is not specified in the valid range of 4M - 2048M inclusive is rejected. DSPSIZE is rejected. | Increased CTRACE and VIT capacity |
| MODIFY VTAMOPTS | V2R1 | When you specify the new PSRETRY IMMED operand value, activation of a TG or a change in the status of a TG triggers immediate path switch processing of HPR pipes. | HPR PSRETRY Enhancement |
