How to Establish Two 802.2 Connections To AS/400

• Microsoft SNA Server for Windows NT, versions 2.0, 2.1 and 2.11

SUMMARY

SNA Server can establish a second connection to the same AS/400 if the second APPC controller is set up as a non-APPN controller and the APPC device is set as non-APPN capable. This article describes how you can establish the second connection.

MORE INFORMATION

To establish a second connection to the same AS/400, do the following:

SNA Server Configuration

1. Use SNA Server Setup to create a new link service with a different SAP than the existing one. For additional information, please see Chapter 3 of the SNA Server Administration Guide and the following article in the Microsoft Knowledge Base:

2. Create a new connection for the link service created in step 1. To do this, enter a valid Remote Network Address and a Local Node ID. Do NOT enter a Network Name, Control Point Name, or Remote Node ID. For additional information, please see Chapter 3 of the SNA Server Administration Guide.

3. Create a new Remote LU for the new connection. To do this, disable automatic partnering for the LU. Verify that the LU name matches the Control Point Name defined on the AS/400. For additional information, please see Chapter 6 of the SNA Server Administration Guide.

4. Create a new Local LU. To do this, disable automatic partnering. Partner with the Remote LU created in step 3 above. For additional information, please see Chapter 6 of the SNA Server Administration Guide.

AS/400 Configuration

1. Create a new controller description. To do this, set all parameters as a standard SNA Server controller, except for the following:

      AS/400 Parameter      Value
      ----------------      -----
      Exchange Identifier   Local Node ID (set up in Step 2 of SNA Server
                            Configuration above)
      Remote Control Point  *ANY
      Initial Connection    *ANS
      LAN DSAP              SAP for new link service (set up in Step 1 of SNA
                            Server Configuration above)
      APPN-capable          *NO
   
   

2. Create a new APPC device description. To do this, set all parameters as a standard SNA Server controller, except for the following:

      AS/400 Parameter      Value
      ----------------      -----
      Remote location       New Local LU Name (set up in Step 4 of SNA Server
                            Configuration above)
      Attached controller   Controller (set up in Step 1 of AS/400
                            Configuration above)
      APPN-capable          *NO
   
   

3. Vary on both the SNA Server controller and the APPC device.

4. Attempt to start the connection. If any one of the configurations above are set up incorrectly, the connection will not be available.

   NOTE: Since the connection is non-APPN capable, any APPN related functions are ignored.
