SNI Replacement [IP Services]

SNI Replacement

The IBM Communications Controller, commonly known as the front-end processor (FEP), has been used for many specific functions during the several decades that it served as a network attachment point for IBM mainframes. Of these, almost all either have been rendered obsolete or are now being done by more modern equipment. The only significant exception to this change is a function known as SNA Network Interconnection (SNI). SNI is the connection, by gateways, of two or more independent SNA networks to allow communication between logical units (LUs) in those networks. In many cases FEPs that were purchased to support hundreds or thousands of networks devices are now being used to support a very small number of attachments to other SNA networks. This may create an extremely inefficient use of resources and a disproportionate cost to benefit. The largest impediment to replacing this technology is usually a result of it being embedded in at least two separate organizations, meaning that both must simultaneously agree to change.

The general advice from Cisco is to replace SNI at the application level. For each business function that is being performed through an SNI connection, there is almost certainly a readily available equivalent solution that uses the open IP protocol for connectivity.

Cisco acknowledges, however, that there are cases where an SNA-based alternative may be more expedient and, equally important, may require less inter-company agreement. This paper addresses these scenarios, first showing the parameters for the typical configuration that uses FEPs at both organizations, and then four alternatives that continue to use SNA but allow either one or both of the organizations to decommission their FEPs.

This paper details the following five SNI and SNI replacement configuration examples:

Back-to-back configuration
Extended Border Node (EBN) over Enterprise Extender (EE) connections
Single-sided (adjacent) SNI configuration
Advanced Peer-to-Peer Networking (APPN) EBN over a Layer 2 SNA link
Casual Connection

Example 1: Back-to-Back Configuration

The back-to-back configuration is the current configuration in many cases. It is included here to show the "before" picture: two gateway Virtual Telecommunications Access Methods (VTAMs) and two gateway Network Control Programs (NCPs) that connect through a null network (see Figure 1). According to recent Cisco surveys, this is the most popular configuration used between client and partner networks.

Figure 1 Back-to-Back Configuration

Replacing a back-to-back SNI connection to a partner's network requires changes to VTAM and changes and additions to the partner's VTAMs, gateway NCP, and subarea path definitions. The source statements for the gateway NCP-NCP04 are as follows:

Example 2: EBN over EE

The next example is APPN EBN on both ends of an EE or High Performance Routing (HPR)/IP connection, with SNA traffic over an IP network (see Figure 2). When completed, the IP network components can be leveraged for use in delivering SNA traffic and consolidating the network infrastructure into one IP network.

Note: If the VTAM Session Management Exit (ISTEXCAA) was previously used in the subarea networks for controlling the establishment of sessions through the network, the VTAM Directory Services Management Exit (DSME) must be used instead.

Example 3: Single-Sided SNI

This example shows a gateway VTAM with a gateway NCP connecting to a gateway VTAM without a gateway NCP (see Figure 3). This configuration is the easiest to configure and define, and cross-network session control is centralized. This configuration should be considered when the organization wants to remove its FEP, cannot find an IP-based application alternative, and the partner will not change to an APPN connection. The nongateway NCP can be replaced with a Cisco CIP- or Channel Port Adapter (CPA)-equipped router using the CSNA channel protocol, and the wide area connection can be LAN to LAN via Data-Link Switching Plus (DLSw+) or Synchronous Data Link Control (SDLC).

Figure 3 Single-Sided (Adjacent) SNI Configuration

In this example, NET05 is removing a FEP and NET01 is not. NET01 will continue to provide the application services for NET05, and NET01 will remove the NCP/3745 that is currently being used for SNI back-to-back connection to NET05. The same LINE16 is used for the SDLC connection to the router, but Token Ring could have been used for this connection.

The following changes are required to move from the null network SNI configuration to the adjacent SNI configuration at the site NET01 where the FEP is being retained:

Change the SDLC LINE/PU definitions
Change the NETWORK statement NETID parameter
Change the NCP PATH definitions
Change the GWPATH statement in the CDRM major node

The following changes are required at the site NET05 where the FEP is being replaced:

Remove the NCP major node from the ATCCONxx VTAM startup list
Add an XCA major node to define the CIP in the router
Change the GWPATH statement in the CDRM major node
Add the VTAM path statement to reflect the more direct SNA route
Attach the Cisco router with CSNA and DLSw+ configured

Note: Because there is a new subarea defined in NCP03, PATH definitions will be added to all the subarea nodes in NET01. PATH definitions for all the subareas in NET01 will also be added to the NCP03 gateway NCP deck.

The changes made to NCP03 are shown in the following statements:

Example 4: APPN EBN

By using APPN, this configuration eliminates any requirement for FEPs. The two different networks are connected using Cisco CIPs to replace the FEP channel connections, and Cisco DLSw+ for reliable wide area transport (see Figure 4). The example also shows dynamic and static cross domain resources (CDRSCs).

Figure 4 APPN Extended Border Node over Layer 2 SNA link

VTAM is a border node, and CONNTYPE is set to APPN. This causes a control point (CP)-to-CP session to start between the two VTAMs. The output from the log on MVSB when dialed is as follows:

The following changes have been made to test CDRDYN=YES on MVSA and CDRDYN=NO on MVSB. The CDRSC on MVSB restricts MVSA access to applications on MVSB via terminals (TCP10055-TCP10058) only. The CDRSC also restricts MVSB access to applications (TSOA,ECHOMVSA) on MVSA. To implement greater session establishment security, VTAM provides a Session Management Exit (SME) and DSME. In a representative size network, the static CDRSC would require a great deal of coordination between networks.

On MVSA the command F NET,VTAMOPTS,CDRDYN=YES was issued and DYNPU=NO was changed to DYNPU=YES in the XCA major node definition. The XCA major node for the CIP is as follows:

Example 5: Casual Connection

Casual Connection is a PU 2.1-to-PU 2.1 connection with no CP-to-CP sessions. Low-Entry Networking (LEN) between two different networks is called Casual Connection. Static CDRSCs are required, and with LEN connections, only LU 6.2 sessions can establish.

Figure 5 Casual Connection

The CONNTYPE was forced to be LEN on the PU. In this case, there is no CP-to-CP session between the VTAMs, and any LUs must be defined to the other VTAM as hard-coded CDRSCs. The output from the log on MVSA when dialed is as follows:

The XCA major node on MVSA is as follows:

 DKXCA44 VBUILD TYPE=XCA

 DKXP44 PORT ADAPNO=0,CUADDR=4400,SAPADDR=04,MEDIUM=RING,TIMER=20

 DKGR44 GROUP ANSWER=ON, X

 AUTOGEN=(10,L,P), X

 CALL=INOUT,DIAL=YES,ISTATUS=ACTIVE

The XCA major node on MVSB is as follows:

 DKXCA43 VBUILD TYPE=XCA

 DKXP43 PORT ADAPNO=0,CUADDR=4300,SAPADDR=04,MEDIUM=RING,TIMER=20

 DKGR43 GROUP ANSWER=ON, X

 AUTOGEN=(10,L,P),CALL=INOUT,DIAL=YES,ISTATUS=ACTIVE

The switched PU major node on NETA.MVSA is as follows:

 DKSW01 VBUILD TYPE=SWNET

 DKPUMVSB PU ADDR=C1,PUTYPE=2,CPNAME=MVSB,XNETALS=YES,NETID=NETD, X

 CONNTYPE=LEN

 PATH DIALNO=0104400075130002,GRPNM=DKGR44

The switched PU major node on NETD.MVSB is as follows:

 DKSW02 VBUILD TYPE=SWNET

 DKPUMVSA PU ADDR=C1,PUTYPE=2,CPNAME=MVSA,XNETALS=YES, X

 NETID=NETA,CONNTYPE=LEN

 PATH DIALNO=0104400075130001,GRPNM=DKGR43

Notice that CONNTYPE=LEN was coded on both PUs. This is because the VTAMs are APPN border nodes, and CONNTYPE=APPN is specified in the VTAM startups (as shown in the statements that follow). So the CONNTYPE had to be overrided in the PU definition, and VTAM V4R4 or later is required to do this. By coding CONNTYPE=LEN, the PU can only be a LEN resource, even if at activation the XID indicates the PU can be an APPN resource. The hard-coded CDRSC major node from NETA.MVSA is as follows:

 DKCDRSC1 VBUILD TYPE=CDRSC

 NETWORK NETID=NETD

 APPCMVB1 CDRSC ALSLIST=(DKPUMVSB),ALSREQ=NO

Every APPLID must be defined to the other VTAM as a CDRSC, as in the previous statements. LU 6.2 sessions only work over a LEN node. The VTAM options output from the VTAMs is as follows:
