Create the SNA controller description

The controller description identifies the remote devices to which the server connects.

Note: If you are running APPN, your server can automatically create the controller description (suggested method) or you can create it manually. Autocreate cannot be used with APPC.

To create a controller description to use with your LAN adapter, complete the following steps:

Optional: Type GO CMDCTL to find a list of controller creation commands.
Type the name of the command to use and press F4 (Prompt).
Type the name of the controller description into the Controller description field.
Specify *LAN in the Link Type field.
Press Enter three times. The server displays more fields that might require the following information:
- Switched line list: specifies one or more line descriptions that your controller description can use. Enter the name of your Ethernet Line Description. For more information about the relationship between the line and controller descriptions, see Connect LAN devices.
- Initial connection: determines whether the controller description initiates connection requests (*DIAL), or waits for incoming connection requests (*ANS).
  If you specify *DIAL and want to adjust the polling duration or frequency, you can change the LAN connection retry (LANCNNRTY) or LAN connection timer (LANCNNTMR) field. See LANCNNTMR and LANCNNRTY for more information.
- LAN remote adapter address: contains the address of the remote input/output adapter (IOA). To locate this address, see View the LAN IOA address. If you are using the preset address of the adapter, consider using your own LAN IOA addresses to minimize your reconfiguration work.
- LAN DSAP: contains the source service access point (SSAP) value from the controller description that is for the remote device. For more information about service access points (SAPs), see SNA connections to LAN protocols.
- LAN SSAP: contains a value from the SSAP listing of the line description that is associated with this controller description.
For detailed information about all the parameters and their dependencies, see the chapter about communications controller descriptions in Communications Configuration.
Fill in all of the required fields. Press Enter until you reach a required field.
Press Enter again to create the description.
