Communication considerations using model controllers

When MDLCTL(*YES) is specified, it is treated differently than other APPC controller descriptions.

The following are some considerations for model controller descriptions:

• Device descriptions cannot be attached to model controllers.
• Model controllers only go to a status of varied on.
• A model controller can be associated with only one line description at a time. This configuration is done using the SWTLINLST parameter in the model controller.
• The RMTNETID, RMTCPNAME, and ADPTADR parameters are optional parameters when MDLCTL(*YES) is specified.
  Note:
  When a communications session is requested and the local system is an end node, the adjacent system must be specified in the NETSERVER parameter of the CHGNETA command in order for the local system to establish CP-CP sessions with the adjacent system.
• Since model controller descriptions do not represent an actual connection, they are not associated with a line description when using the Work with Configuration Status (WRKCFGSTS) command.

To configure a model controller description, specify MDLCTL(*YES) in an APPC controller description.
