This topic provides the following information:

• A description of the process used by the sample exit to identify the switched major node name and the names of dynamic switched devices. If you write your own exit, you can modify the process.
• Guidelines for modifying the sample exit's name generation function.
• A description of the CSDATA file that the exit can write to when the connection status feature of the exit is active.

A configuration services XID exit routine allows you to:

• Provide VTAM® information to create dynamic representations of switched devices and switched major nodes without disrupting a switched network.
• Record connection and disconnection times for switched PUs.
• Tell VTAM to process or deny a request for contact (REQCONT) from a switched device that is already defined to VTAM.
• Tell VTAM to process or deny a request for PU activation (REQACTPU) from a predefined switched device that is supported by DLUR.
