Synchronous Link Control Link Trace Package

The synchronous link control (SLC) link trace package is a diagnostic tool you can use to maintain SLC communication lines and to provide statistics about them. It provides a sequential record of all data blocks and line control blocks (LCBs), both input and output, on all links. For each data block or LCB, a record containing the following information is written to the link trace (LKT) tape:

The LKT tape is processed by the SLC link trace postprocessor, which formats the output.

Use the ZLKTN and ZLKTF commands to start and stop the SLC link trace. For more information about these commands, see TPF Operations.

The SLC link trace can be active across a state change.
