Configure SNA over token ring

To Configure Systems Network Architecture (SNA) over token ring, you need to create the token-ring line description, the controller description, and sometimes the device description.

1. Create the token-ring line description. Ensure the correct configuration of these fields when you create the line description:
   • If the system uses this line description to communicate with an SNA host through a parallel connection, define a value other than *LIND in the Exchange identifiers field.
   • Advanced Peer-to-Peer Networking (APPN) and Advanced Program-to-Program Communication (APPC) connections use fields Link speed through Autodelete controller. You can use the defaults or press F1 (Help) for more information about each field.
   • If you want the system to create the APPC controller description when a call comes in, specify *YES in the Autocreate controller field. If you specified *YES, skip to step 3.
2. Create the controller description.
3. If your controller description does one of these, you must create a device description:
   • Specifies *NONE in the Autocreate device field.
   • Specifies *NO in the APPN-capable field (this applies only to APPC controller descriptions)
4. Enable the descriptions to accept connections.

• Create the token-ring line description
  To create a token-ring line description, use the Create Line Description command and follow a series of steps.
• Create the SNA controller description
  The controller description indicates the remote devices to which the system connects.
• Create the SNA device description
  The device description describes the communications device used by the remote device.
