1 SNA Links Overview HP e3000 users can communicate with an IBM SNA remote system by using one of the Hewlett-Packard SNA link products: • SNA/SDLC Link/iX (referred to as SNA/SDLC Link), which works with the SNA services to provide an HP e3000-to-IBM host or AS/400 connection over an SNA network. • SNA/X.25 Link/iX (referred to as SNA/X.25 Link), which works with the SNA services to provide an HP e3000-to-IBM host or AS/400 connection over an X.25 network.
SNA Links Overview SNA Layers Implemented SNA Layers Implemented The SNA services implement the upper layers of the SNA architecture. SNA Transport implements a type 2.0 (T2.0) node (formerly called a Physical Unit Type 2 [PU.T2]) and type 2.1 (T2.1) node (formerly called a Physical Unit Type 2.1 [PU 2.1]) for SNA/SDLC Link, a T2.0 node for SNA/X.25 Link, and a T2.0 and T2.1 for SNA/Token Ring Link. (Note that, at this time, LU 6.2 API/XL is the only SNA service that makes use of the T2.
SNA Links Overview Tracing Provided Tracing Provided Three levels of tracing for the SNA links are provided: node tracing, intrinsic tracing, and link-level tracing. Node tracing for SNA Transport is on a node basis and normally is turned off. When turned on, it traces SNA Transport internal events; so, it is a useful tool for troubleshooting SNA Transport. Intrinsic tracing is on a session basis and normally is turned off.
SNA Links Overview Other SNA Transport Functions Provided Other SNA Transport Functions Provided Besides tracing, SNA Transport also provides these basic services through the MPE command interpreter: • Starting and stopping an SNA node (see Chapter 5 , “SNA Link Troubleshooting,” and Chapter 6 , “MPE Commands.”) • Session and link status (see Chapter 6 , “MPE Commands.”) • Software version listing (see Chapter 6 , “MPE Commands.
SNA Links Overview SNA/SDLC Link Overview SNA/SDLC Link Overview SNA/SDLC Link is composed of hardware and software: • Programmable Serial Interface card (PSI) or Advanced Communication Controller card and cables (hardware) • SNA Transport (software) • SDLC or SDLCMUX link driver (software) The hardware of SNA/SDLC Link (the PSI and cables) and the downloaded SNA Transport software implement the Physical Control layer of SNA, and the SDLC or SDLCMUX link driver implements the Data Link Control layer.

2 SNA Node and Link Configuration This chapter describes how to use the NMS configuration manager (NMMGR) to create or modify a hierarchical configuration file for the SNA node and link. To configure an SNA service, see the Node Manager’s Guide for that service.
SNA Node and Link Configuration Network Configuration Order Network Configuration Order We recommend that the HP e3000 system and the software components of the IBM host or AS/400 system be configured in this order: 1. The IBM host (JES2, JES3, VTAM, NCP, etc.) or AS/400 system. 2. The SNA nodes on the HP e3000. 3. Logging for SNA Transport on the HP e3000. 4. The SNA services on the HP e3000. 5. Logging for the SNA services on the HP e3000. NOTE For SNA/X.25 Link, the X.
SNA Node and Link Configuration Host Configuration Overview Host Configuration Overview Before communication between the HP e3000 and the IBM SNA host system is possible, both systems must be configured. The host configuration should be done first, and it consists of changes to the system generations of one or more of the following, as applicable for the SNA link being used: • ACF/NCP • ACF/VTAM • X.
SNA Node and Link Configuration AS/400 Configuration Overview AS/400 Configuration Overview Before communication between the HP e3000 and the IBM SNA AS/400 system is possible, both systems must be configured. The AS/400 configuration should be done first, and it consists of specifying values for certain parameters. The AS/400 configuration must be coordinated with the SNA node configuration on the HP e3000. Coordination between the AS/400 system and the SNA services also must be done.
SNA Node and Link Configuration HP e3000 Configuration Overview HP e3000 Configuration Overview Once the IBM remote system is configured, you can configure the HP e3000 system. Configuration of the HP e3000 system is accomplished through the Node Management Services configuration manager (NMMGR). The configuration consists of the creation of a configuration file, using NMMGR.
SNA Node and Link Configuration Data Required from the Host Configuration Data Required from the Host Configuration Data in an SNA node configuration file must correspond to information from the host configuration. So, before using NMMGR, you should have certain information from the host configuration. The host information that corresponds to SNA node configuration information for SNA/SDLC links, SNA/X.25 links, and SNA/Token Ring links is described below.
SNA Node and Link Configuration Data Required from the Host Configuration permanent virtual circuits (PVCs). Each NMMGR screen field is described later in this chapter. Table 2-2 Host Macro Values for X.25 Link PVC Host Configuration Macro and Operand Field in NMMGR Screen SNA Node NMMGR Screen X25.LINE TYPE Virtual Circuit Type X.25 Link Data X25.
SNA Node and Link Configuration Data Required from the Host Configuration Table 2-4 Host Macro Values for X.25 System Access Host Configuration Macro X25.OUFT INDEX Field in NMMGR Screen Set Name Network Services NMMGR Screen X.25 User Facility Sets Note that once the facility set to be used by SNA/X.25 Link is specified in the INDEX operand of the X25.OUFT host macro, it must also be referenced by the OUFINDX operand of the X25.LINE host macro.
SNA Node and Link Configuration Data Required from the Host Configuration SNA/Token Ring Information For the host and the HP e3000 to communicate, you must coordinate the SNA/Token Ring node configuration with the ACF/NCP and ACF/VTAM host configurations. The HP SNA Products Remote System Configuration Guide explains these configurations. Table 2-7 shows the relationships between items from the host configuration and items in the SNA node configuration file for an SNA/Token Ring link.
SNA Node and Link Configuration Data Required from the AS/400 Configuration Data Required from the AS/400 Configuration Data in an SNA node configuration file must correspond to information from the remote AS/400 type 2.1 parameters. So, before using NMMGR, you should have certain information from the AS/400 configuration. The AS/400 information that corresponds to SNA node configuration information for SNA/SDLC links, SNA/X.25 links, and SNA/Token Ring links is described below.
SNA Node and Link Configuration Data Required from the AS/400 Configuration Table 2-9 AS/400 Parameter Values for X.25 Link AS/400 Configuration Parameter NETADDR in the line description Field in NMMGR Screen NMMGR Screen Name X.25 Link Data Remote’s X.25 Network Address SNA/Token Ring Information For the AS/400 and the HP e3000 to communicate, you must coordinate the SNA/Token Ring node configuration with the AS/400 configuration.
SNA Node and Link Configuration NMMGR Configuration Overview NMMGR Configuration Overview The SNA node and link configuration is done by using NMMGR to create or modify a configuration file. The file contains this information: • SNA node information: used by SNA Transport to manage sessions with the host. • Link information: used for SDLC data link control and phone data (for switched lines), X.25 link information, and token ring link information.
SNA Node and Link Configuration NMMGR Configuration Overview For dependent LUs and independent LUs, you must provide information for the LU-LU sessions. For each LU defined in SNA Transport, an LU must be defined in the host’s NCP/VTAM configuration. You must configure each LU and establish a correspondence with an LU in the NCP/VTAM configuration. You configure these items for an SNA node: • Node identification. This information identifies the node to the host and specifies the type of node (T2.0 or T2.
SNA Node and Link Configuration NMMGR Configuration Overview Configuration File Validation Validating the configuration file ensures that the configuration data is logically and syntactically correct. Each SNA service’s data is also checked against the SNA node configuration data for correctness (for example, correct LU names). See each service’s Node Manager’s Guide for that service’s validation error messages.

4 SNA Node Startup and Shutdown This chapter describes how SNA sessions are established with the IBM remote system, how SNA nodes are started up and shut down, and how SNA sessions are terminated. These topics are covered in this chapter: • Establishing sessions with the remote system — For a type 2.0 node — For a type 2.
SNA Node Startup and Shutdown Establishing Sessions with the Remote System Establishing Sessions with the Remote System Remote system session establishment is slightly different for a type 2.0 (T2.0) node than for a type 2.1 (T2.1) node. Session establishment for each node type is explained below, and examples of session establishment activities between the HP e3000 and the IBM remote system are shown later in this chapter.
SNA Node Startup and Shutdown Establishing Sessions with the Remote System manage the LU-LU sessions on the HP e3000. For a Type 2.1 Node Session establishment for a T2.1 node is different than establishment for a T2.0 node in one major way: An independent LU on a T2.1 node can establish an LU-LU session with a remote system LU without the need for a corresponding LU-SSCP session.
SNA Node Startup and Shutdown Establishing PU-SSCP Sessions on the HP e3000 Establishing PU-SSCP Sessions on the HP e3000 For each node you configure on the HP e3000, a corresponding T2.0 or T2.1 node should be in the remote system configuration. Figure 4-1, “PU-SSCP Session Establishment,” shows how a session is established between the SSCP on the remote system and the PU on the HP e3000 node (either a T2.0 node or a T2.1 node).
SNA Node Startup and Shutdown Establishing PU-SSCP Sessions on the HP e3000 Figure 4-1 PU-SSCP Session Establishment IBM Remote System HP e3000 (T2.0/T2.1 Node) Link started up from remote system SSCP polls for null XID null XID poll - - - - - -> If HP e3000 is a T2.0 node, it sends an XID0 If HP e3000 is a T2.
SNA Node Startup and Shutdown Establishing LU-SSCP Sessions on the HP e3000 Establishing LU-SSCP Sessions on the HP e3000 For a dependent LU on the HP e3000 to communicate with another dependent LU, it must first have a session with the SSCP on the host system. Each LU-SSCP session is managed by SNA Transport. Figure 4-2, “LU-SSCP Session Establishment,” shows LU-SSCP session establishment with SNA Transport acting as the LU service manager.
SNA Node Startup and Shutdown Terminating SNA Sessions Terminating SNA Sessions PU-SSCP and LU-SSCP sessions can be terminated from the remote system by deactivating an LU, the PU, or the link. Also, the SNA link terminates all sessions on the HP e3000 node if the link is unexpectedly interrupted or deactivated. An HP e3000 SNA node can be intentionally shut down with the SNACONTROL STOP command (see Chapter 6 , “MPE Commands,” of this manual); any SNA services that are running are also terminated.

5 SNA Link Troubleshooting You can troubleshoot the SNA links by using the tracing and logging facilities. This chapter describes those facilities and other related topics: • The tracing facility — SNA Transport tracing — Link-level tracing • The logging facility — SNA Transport logging — Link-level logging • Using NMDUMP for the SNA links — SNA Transport output formats — SDLC link output formats — X.
SNA Link Troubleshooting The Tracing Facility The Tracing Facility Tracing provides data for analysis, and can be done on many levels. The highest level of tracing is at the services level (see the Node Manager’s Guide for each service for which tracing is available). SNA tracing is done at the SNA Transport level (an intermediate level) and at the link level (the lowest level). All of these functions are controlled through MPE commands (see Chapter 6 , “MPE Commands,” in this manual).
SNA Link Troubleshooting The Tracing Facility NOTE Although the format of the default trace file name is the same for all types of tracing, the same default file name will not be assigned for more than one trace. This is because the default trace file name is automatically assigned in numerical order. For example, suppose the last default trace file name assigned was NMTC0004.PUB.SYS. If you started SNA Transport intrinsic tracing, and did not specify a trace file name, the default name NMTC0005.PUB.
SNA Link Troubleshooting The Tracing Facility NOTE Although the format of the default trace file name is the same for all types of tracing, the same default file name will not be assigned for more than one trace. This is because the default trace file name is automatically assigned in numerical order. For example, suppose the last default trace file name assigned was NMTC0004.PUB.SYS. If you started SNA Transport intrinsic tracing, and did not specify a trace file name, the default name NMTC0005.PUB.
SNA Link Troubleshooting The Tracing Facility NOTE Regardless of whether you specify a trace file name or let the default name be assigned, the trace file that is opened when tracing is started is used until tracing is stopped. This means that if the file becomes full before tracing is stopped, the current contents of the file are overwritten with the new trace information, starting at the beginning of the file (no warning is issued).
SNA Link Troubleshooting The Logging Facility The Logging Facility Logging records subsystem events — significant normal events, as well as error events — for use in problem determination and monitoring network usage and resources. NMS performs SNA link logging| at two levels: for the SNA network (SNA Transport logging), and at link level (SDLC link logging, X.25 link logging, Token Ring link logging, and link trace logging).
SNA Link Troubleshooting The Logging Facility — Bad port messages • CLAS0012: LU-LU activities — OpenUser/CloseUser — Session activation/Session deactivation • CLAS0013: LU-SSCP activities — OpenUser/CloseUser — Session activation/Session deactivation Link-level Logging Four types of link-level logging are available: SDLC link logging, X.25 link logging, Token Ring link logging, and link trace logging.
SNA Link Troubleshooting The Logging Facility Token Ring Link Logging Token ring link logging records informational messages and error messages generated by the token ring link. It is controlled through the MPE commands SHOWNMLOG, SWITCHNMLOG, and RESUMENMLOG. These commands enable the node manager to determine the number of and available space in the current NM log file (NMLGnnnn.PUB.
SNA Link Troubleshooting Using NMDUMP for the SNA Links Using NMDUMP for the SNA Links The NMS utility NMDUMP can be used to format tracing and logging records for the SNA links. Described below are the tracing and logging formats produced for the SNA links by NMDUMP. Note that NMDUMP is described in more detail in Using the Node Management Services Utilities. If you are not familiar with NMDUMP, you should read that manual before running NMDUMP.

SNA Link Troubleshooting Problem Resolution Problem Resolution Problems that can occur while installing, configuring, and running an SNA link — and how to deal with them — are described here. Guidelines for submitting a change request (CR) are also given. Common Problems Some problems are common to many situations — invalid software installation, version incompatibilities, insufficient MPE resources, corrupt configuration files, and file system errors.
SNA Link Troubleshooting Problem Resolution Corrupt Configuration File The configuration file might be corrupt. Validate the configuration file to check for possible corruption. If the error persists, use NMMGR to manually check the configuration file (if possible). If bad records seem to be localized to a particular item, delete that item and reconfigure it. If necessary, RESTORE a backup copy of the file.
SNA Link Troubleshooting Problem Resolution can be defined in a higher-level macro, this structure must be followed: GROUP, LINE, SERVICE, PU, and LU. A macro could be missing a required operand or an invalid operand might have been specified for a particular macro. Installation Problems Some common problems that might occur during installation, or as a result of improper or unsuccessful installation, are described below. 1. Inactive VTAM node.
SNA Link Troubleshooting Problem Resolution Common Information For any CR, include this common information, where applicable: • A characterization of the problem. Describe the events leading up to and including the problem. Try to describe the source of the problem. Describe the symptoms of the problem. Your characterization should include MPE commands, communication subsystem commands, job streams, result codes and messages, and data that can reproduce the problem.
SNA Link Troubleshooting Problem Resolution • Always obtain a copy of the generation of the host system you are using for ACF/VTAM and ACF/NCP. For the host system to be compatible with the SNA link, Hewlett-Packard sets certain operands and parameters to required values (see Chapter 2 , “SNA Node and Link Configuration,” of this manual). Note any differences between the actual system generation and your expectations. Keep this information for your Hewlett-Packard support contact. This is very important.
SNA Link Troubleshooting Problem Resolution and this trace file to your Hewlett-Packard support contact for analysis. NOTE It is important to give a copy of the PSI dump that took place while link-level tracing was enabled to your Hewlett-Packard support contact for analysis. • If a PSI failure has not taken place, turn on link-level tracing with the MPE command SNACONTROL START or SNACONTROL TRACEON (see Chapter 6 , “MPE Commands,” of this manual).

6 MPE Commands This chapter describes, in alphabetical order, the MPE commands related to SNA Transport. You must have MPE node manager (NM) capability to use these commands. Table 6-1 summarizes the functions of the commands. Table 6-1 MPE Command Summary Command Function RESUMENMLOG Resumes NM logging after a recoverable error. SHOWNMLOG Displays the identification number and available space of the NM log file. SNACONTROL AUTODIAL Causes an SNA node's auto-dial modem to dial.
MPE Commands RESUMENMLOG RESUMENMLOG Resumes NM logging after a recoverable error. Syntax RESUMENMLOG Use RESUMENMLOG can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Description RESUMENMLOG resumes logging to the NM log file (NMLGnnnn.PUB.SYS) after it was suspended because of a recoverable I/O error, once the error has been corrected. For example, assume that the system is on line, NM logging is enabled, and a recoverable error occurs.
MPE Commands SHOWNMLOG SHOWNMLOG Displays the identification number and available space of the NM log file. Syntax SHOWNMLOG Use SHOWNNMLOG can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Description SHOWNMLOG displays the number of the current NM log file (NMLGnnnn.PUB.SYS) and the percentage of available file space currently used.
MPE Commands SNACONTROL AUTODIAL SNACONTROL AUTODIAL Causes an SNA node’s auto-dial modem to dial. Syntax SNACONTROL AUTODIAL;NODE=NodeName Use SNACONTROL AUTODIAL can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Parameter NodeName Conditionally required. The name of the active SNA node you want to cause to automatically dial. The name can be up to eight alphanumeric characters long; the first character must be alphabetic.
MPE Commands SNACONTROL AUTODIAL Example SNACONTROL AUTODIAL;NODE=IBMNODE The auto-dial modem configured for node IBMNODE is caused to dial.
MPE Commands SNACONTROL START SNACONTROL START Starts an SNA node, link-level tracing, and SNA Transport node tracing. Syntax SNACONTROL START;NODE=NodeName [;LINKTRACE[=[TraceType][,TraceFile]]] [;NODETRACE[=TraceFile]] [;ERROPT=ErrorOption] [;TFILESIZE=NumRecords] Use SNACONTROL START can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Parameters NodeName Conditionally required. The name of the configured SNA node you want to start.
MPE Commands SNACONTROL START error will occur. If you do not specify an account for a link-level trace file, the file will automatically be written to the SYS account. If you specify a file that does not exist, NMS builds a new one and opens it to record tracing. If you specify an existing file that NMS does not currently have open to record tracing, NMS will overwrite the file’s previous contents; no warning is issued.
MPE Commands SNACONTROL START If you are using a manual-dial modem, you can begin to dial after this logging message is displayed on the console: Node NodeName ready for activation by host Note that if you are using a manual-dial modem, console logging for SNA Transport logging class CLAS0013 must be enabled (see Chapter 3 , “Logging Configuration,”) so that the above message can be displayed. Also, note that once a node is active, reissuing this command for that node causes an error.

MPE Commands SNACONTROL STATUS • CONNECTED LEVEL 1 = A level 1 connection has been established. • CONNECTED LEVEL 2 = A level 2 connection has been established. • CONNECTING LEVEL 1 = A level 1 connection is in progress. • CONNECTING LEVEL 2 = A level 2 connection is in progress. • DISCONNECTING LVL 1 = A level 1 disconnection is in progress. • DISCONNECTING LVL 2 = A level 2 disconnection is in progress. • ERROR = The SDLC link driver has detected a link error. The physical path is the address of the PSI.
MPE Commands SNACONTROL STATUS The local timeout is the number of seconds the SDLC link driver will wait for PSI card activity before reporting a PSI failure. The transmission speed is the transmission speed (in bits per second) of the line being used by the link if a modem is not being used. If a modem is being used, the modem determines the speed. The connect duration is how long a level 2 connection has been maintained.
MPE Commands SNACONTROL STATUS Receive overruns is the total number of received frames that contained no control bytes. CRC errors is the total number of received frames that contained a Cyclical Redundancy Check (CRC) error. Statistics resets is the total number of times the statistics have been cleared. X.25 Link-Level Status Information Two examples of X.25 link-level status displays are given below, and the terminology used is described after the examples.
MPE Commands SNACONTROL STATUS where IBMNODE is already active, and a permanent virtual circuit (PVC) is being used, could generate this display: LINKNAME : IBMNODE SNA CONNECTED TRACING LINKTYPE : SNA X.25 : ON LINKSTATE: TRACEFILE: TRACE.PUB.
MPE Commands SNACONTROL STATUS Example 2 If an X.25 link is being used, typing SNACONTROL STATUS;NODE=IBMNODE;LINK=ALL where IBMNODE is already active, and a switched virtual circuit (SVC) is being used, could generate this display: LINKNAME : IBMNODE SNA CONNECTED TRACING : ON LINKTYPE : SNA X.25 LINKSTATE: TRACEFILE: TRACE.PUB.
MPE Commands SNACONTROL STATUS Terminology The linkname is the same as the node name. The linktype is “SNA X.25”. The linkstate is one of the following: • SNA CONNECT PENDING = The virtual circuit to the remote system has been established and an SNA connection (which must use the virtual circuit) is in the process of being established. • SNA CONNECTED = The SNA and X.25 connections to the remote system have been established. • SNA DISCONNECT PENDING = The SNA connection is in the process of terminating.
MPE Commands SNACONTROL STATUS without success. Note that this information is displayed for an outgoing SVC only. The call retry delay is the number of seconds the QLLC module will wait between attempts to connect to the remote system. Note that this information is displayed for an outgoing SVC only. The call retry count is the number of times call retries have been attempted. Note that this information is displayed for an outgoing SVC only.
MPE Commands SNACONTROL STATUS where IBMNODE is already active could generate this display: Linkname: IBMNODE CONNECTED Physical Path: Linktype: IEEE8025 48 Linkstate: Data Rate: 16 Mbps Current Station Address: Default Station Address: Functional Address Mask: 10-00-90-00-00-07 10-00-90-90-C8-46 00-00-00-00 Transmits no error: Transmit byte count: Transmit errors: 6614976 2368752825 0 Receives no error: Receives byte count: Receive errors: 6620830 2367702513 0 NAME ======== XPORTPU XPORTLU XPOR
MPE Commands SNACONTROL STATUS The current station address is the currently-active station address. The default station address is the factory-configured default station address. The function address mask is the address mask as described in the IBM Token-Ring Network Architecture Reference. Transmits no error is the number of frames transmitted without errors. Receives no error is the number of frames received without errors. Transmit byte count is the number of bytes transmitted without errors.
MPE Commands SNACONTROL STATUS Terminology The name is the PU or LU name. Note that XPORTPU and XPORTLU are the internal names that are used by SNA Transport. XPORTPU is a PU name used for maintaining the PU-SSCP session. XPORTLU is the LU name used for maintaining the LU-SSCP sessions (for dependent LUs). The type is the type of the session. This is either PU-SSCP for PU-SSCP sessions, LU-SSCP for LU-SSCP sessions, DEP_LU for dependent LU-LU sessions, or IND_LU for independent LU-LU sessions.
MPE Commands SNACONTROL STATUS • PEND_SON = Pending session outage notification. A Session Outage Notification (SON) deactivation request has been generated internally or received on the link. However, no response has been sent. • RESET = The initial state. No sessions exist. The user is the name of the user or program that owns the session. The trace file is the name of the trace file, if tracing has been turned on. If tracing is off, OFF is displayed.
MPE Commands SNACONTROL STOP SNACONTROL STOP Stops an SNA node and all activity on the node. Syntax SNACONTROL STOP;NODE=NodeName[;TYPE=StopType] Use SNACONTROL STOP can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Parameters NodeName Conditionally required. The name of the active SNA node you want to stop. The name can be up to eight alphanumeric characters long; the first character must be alphabetic.
MPE Commands SNACONTROL STOP • Q = (Quiesce) The node is stopped in an orderly way. SNA Transport notifies the SNA services that it is stopping. Each service completes sending and receiving all active data sets. As the LUs become inactive, the services stop the LU-LU sessions, and SNA Transport stops the LU-SSCP sessions. Then, SNA Transport shuts down the PU-SSCP session.
MPE Commands SNACONTROL STOPSESS SNACONTROL STOPSESS Stops an LU-LU session without stopping the SNA node. Syntax SNACONTROL STOPSESS;NODE=NodeName;LUNAME=LUName [;TYPE=StopType] Use SNACONTROL STOPSESS can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Parameters NodeName Conditionally required. The name of the active SNA node the LU-LU session is on.
MPE Commands SNACONTROL STOPSESS • Q = (Quiesce) The session is stopped in an orderly way. SNA Transport notifies the SNA services that it is stopping the specified LU. Each service completes sending and receiving all active data sets in the LU-LU session. Once the session is stopped, a logging message specifying that the LU-LU session has terminated is generated. Default: Q Description SNACONTROL STOPSESS stops an LU-LU session without stopping the SNA node.
MPE Commands SNACONTROL TRACEOFF SNACONTROL TRACEOFF Turns off link-level tracing, and SNA Transport node tracing. Syntax SNACONTROL TRACEOFF;NODE=NodeName;LINKTRACE ;NODETRACE ;INTRINSIC=LUName Use SNACONTROL TRACEOFF can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Parameters NodeName Conditionally required. The name of the active SNA node for which you want to turn tracing off.
MPE Commands SNACONTROL TRACEOFF Description SNACONTROL TRACEOFF turns off link-level tracing (with the LINKTRACE parameter), SNA Transport intrinsic tracing (with the INTRINSIC parameter, and SNA Transport node tracing and NS over SNA tracing (with the NODETRACE parameter). Note that SNA Transport node tracing is also turned off with SNACONTROL STOP. Tracing is described in Chapter 5 , “SNA Link Troubleshooting,” of this manual. NOTE You must specify at least one type of tracing.
MPE Commands SNACONTROL TRACEON SNACONTROL TRACEON Turns on link-level tracing, SNA Transport intrinsic tracing, and SNA Transport node tracing. Syntax SNACONTROL TRACEON;NODE=NodeName [;LINKTRACE[=[TraceType][,TraceFile]]] [;INTRINSIC=LUName[,TraceFile]] [;NODETRACE[=TraceFile]] [;TFILESIZE=NumRecords] Use SNACONTROL TRACEON can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Parameters NodeName Conditionally required.
MPE Commands SNACONTROL TRACEON contents; no warning is issued. If you specify an existing file that NMS already has open to record tracing (even if it is recording events from a different subsystem), NMS will record trace events for this subsystem to the file in addition to the events that it is currently recording. This allows you to record tracing events from several subsystems to a single file. Default: NMTCnnnn.PUB.
MPE Commands SNACONTROL TRACEON displayed, and the command would have to be reissued with the proper NODE=NodeName parameter included. SNACONTROL TRACEON;LINKTRACE=,TF01 Partial (the default) link-level tracing is to be started for the only active SNA node, and the trace data is to be written to the file TF01.
MPE Commands SNACONTROL VERSION SNACONTROL VERSION Identifies the software version of SNA Transport, SNA/X.25 Link, and SNA/Token Ring Link. Syntax SNACONTROL VERSION Use SNACONTROL VERSION can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command. Description SNACONTROL VERSION identifies versions of SNA Transport program files, NL procedures, and SL procedures, as well as the overall version. It also identifies versions of the SNA/X.
MPE Commands SNACONTROL VERSION Example Typing SNACONTROL VERSION generates a display like this: SNA TRANSPORT 32098-20023 module versions: NL NL NL NL NL procedure: procedure: procedure: procedure: procedure: SNACMD_VERS SNAINTR_VERS SNATC_VERS SNAPC_VERS SNACBACCS_VERS NL SL NL NL SL NM NM NM NM NM procedure: SNAUTIL_VERS procedure: SNACMSTUB_VERS procedure: SNANMSTUB_VERS procedure: SNANMFMT_VERS procedure: SNACMFMT_VERS program file: SNASSV.PUB.SYS program file: SNACSC.PUB.

B NetView Alerts This appendix describes NetView alerts, and how they are sent from your HP e3000 to the IBM remote system.
NetView Alerts Overview Overview A NetView alert is information that is sent to the IBM remote system to tell the IBM operator that an error or problem has occurred on the HP e3000. (Note that NetView must be running on the IBM remote system.) So, be aware that the IBM operator might contact you to check on the status of the HP e3000 system if an alert is received at the remote system console.
NetView Alerts How Alerts Are Sent How Alerts Are Sent When an alert is generated (by either SNA Transport or an HP e3000 operator), it is stored in an MPE message file named nodename.PUB.SYS (where nodename is the name of the configured SNA node the alert is to be sent to). SNA Transport continually checks the message files for alerts. When it finds an alert in a message file, it sends the alert to the remote system and waits for an acknowledgment that the remote system received it.
NetView Alerts Creating the Message File Creating the Message File To enable SNA Transport to send alerts (generated by itself or an operator) to NetView, you must create the message file the alerts will be stored in. To create the file, type this command at the MPE system prompt: BUILD NodeName.PUB.SYS;MSG NodeName is the name of the configured SNA node the alerts are to be sent to. You must create a message file for each SNA node you will want alerts to be sent to.
NetView Alerts SNA Transport-Generated Alerts SNA Transport-Generated Alerts A set of alerts that SNA Transport generates have been predefined for these conditions: • Configuration or customization error — Bad phone number • Link error — Dial not completed, unknown automatic-dial error, or data line busy — No ACU power, or cable is missing — Datacomm line was lost — Internal error occurred Note that a logging message for each of these conditions is also generated.
NetView Alerts Operator-Generated Alerts Operator-Generated Alerts Anyone can generate an alert to be sent to the IBM remote system operator (no special user capabilities are needed). This function can be used for sending error-related information that might not be automatically reported by error detection programs and utilities. To be able to generate alerts, ensure that a message file exists for each SNA node you want to send alerts to (see “Creating the Message File” earlier in this appendix).
NetView Alerts Operator-Generated Alerts See Appendix A , “Messages,” for the error messages that can occur when you send an operator-generated NetView alert.
