Create an APPC controller description

A controller description defines the adjacent systems in the network.

• The use of Advanced Peer-to-Peer Networking® (APPN) support is indicated by specifying APPN(*YES) when creating the controller description.
• The use of high-performance routing (HPR) support is indicated by specifying HPR(*YES) when creating the controller description.

To create controller descriptions, do the following:

1. Type one of these commands on any iSeries™ command line for the type of controller you need to define and press F4.
   • Create Controller Description (APPC) (CRTCTLAPPC)
   • Create Controller Description (Systems Network Architecture (SNA) HOST) (CRTCTLHOST)
2. Use the online help information to choose the correct parameter values.
3. Press Enter. The controller description is created.

To specify AnyNet® support, you must specify *ANYNW on the LINKTYPE parameter of the CRTCTLAPPC command. To specify Enterprise Extender support (SNA over IP using HPR), you must specify *HPRIP on the LINKTYPE parameter of the CRTCTLAPPC command. Use the online help information to choose the correct parameter values.

• The AUTOCRTCTL parameter on a token-ring, Ethernet, wireless, or distributed data interface (DDI) line description is set to *YES.
• The system receives a session start request over the line from a system without an existing controller.
