Establishing a session using Communications Server for AIX V5

Verify the level of Communications Server software you have installed by entering the AIX command:

lslpp -h sna.rte

The level displayed in the response needs to be at least Version 5.0.

To update the SNA configuration profile, you need root authority. (Without root authority you can display options and appear to modify them, but cannot actually make any changes.) You can make configuration changes when SNA is either active or inactive.

The configuration scenario that follows was accomplished using the graphical interface.

Note:

The setup used is APPN using independent LUs.

If you are an experienced user of AIX, you may choose to circumvent the panels and use the command-line interface. Refer to the SNA Server for AIX Configuration Reference manual to see the commands that correspond to the panels illustrated.

Throughout the following example, only the panels for profiles that must be added or updated are shown.

Configuring your node

This configuration uses a token ring setup. To define the end node to connect to the network node (assuming that a network node already exists), you need to:

1. Click on Services from the main menu on the main window.
2. Select Configuration node parameters ... from the drop-down list. A window entitled Node parameters appears:

   
   
   
   

3. Click on End node for APPN support.
4. In the SNA addressing box, enter a name and alias for the Control point. The Control point name consists of a Network name ((1)) and a Control point name ((2)).
5. Enter the Node ID ((3)) of your local machine.
6. Click on OK.

You have now configured your node to connect to the network node.

Configuring connectivity to the network

1. Defining your port:
   1. From the main menu of the main window, click on Services, Connectivity, and New port ... A window entitled Add to machine name screen appears.
   2. Select the default card for connecting to the network (Token ring card).
   3. Click on OK. A window entitled Token ring SAP appears:

      
      
      
      

   4. Enter a port name in the SNA port name box, for example, MQPORT.
   5. Check Initially Active.
   6. Click on OK.
2. Defining your connection to the network node:
   1. From the main menu on the main window, click on Services, Connectivity, and New link station ...
   2. Click on OK to link your station to the chosen port (MQPORT). A window entitled Token ring link station appears:

      
      
      
      
      

   3. Enter a name for your link station ((4)), for example, NETNODE.
   4. Enter the port name to which you want to connect the link station. In this case, the port name would be MQPORT.
   5. Check Any in the LU traffic box.
   6. Define where the remote node is by entering the control point on the network node in the Independent LU traffic box. The control point consists of a Network name ((10)) and a CP name of adjacent node ((17)).

      Note:

      The network node does not have to be on the remote system that you are connecting to.

   7. Ensure the Remote node type is Network node.
   8. In the Contact information, enter the MAC address ((15)) of the token ring card on the network node.

      Note:

      The network node does not have to be on the remote system that you are connecting to.

   9. Click on Advanced .... A window entitled Token ring parameters appears:

      
      
      
      
      

   10. Check Remote node is network node server.
   11. Click on OK. The Token ring link station window remains on the screen.
   12. Click on OK on the Token ring link station window.

Defining a local LU

To define a local LU:

1. From the main menu on the main window, click on Services, APPC, and New independent local LU .... A window entitled Local LU appears:

   Figure 33. Local LU window
   
   
   
   

2. Enter an LU name ((4)) and alias ((5)).
3. Click on OK.

You have now set up a basic SNA system.

To define the mode controlling the SNA session limits:

1. From the main menu in the main window, click on Services, APPC, and Modes .... A Modes window appears.
2. Select the New ... button. A window entitled Mode appears:

   Figure 34. Mode window
   
   
   
   

3. Enter a Name ((9)) for your mode.
4. When you are happy with the session limits, click on OK. The Modes window remains on the screen.
5. Click on Done in the Modes window.
