LCSx entry for LAN channel station error (Part 1)

Entry:: LCSL, LCSP, LCSS, or LCSX
VIT option:: LCS
Event:: LAN channel station error (Part 1)
VIT processing module:: ISTRACLS
Control is returned to:: The module that issued the INTRACE

If the LCS trace option is specified, an LCSX trace record is created for every data frame VTAM® receives from or sends to an IBM® 3172 Interconnect Nways Controller.

If the VIT is active and VTAM receives a frame that is not valid from an IBM 3172 Interconnect Nways Controller, an LCSL, LCSP, or LCSS trace record is created depending on the following error conditions.

The LCSL trace record is created when VTAM receives link-related data that is not valid.
The LCSP trace record is created when VTAM receives adapter-related data that is not valid.
The LCSS trace record is created when VTAM receives SAP-related data that is not valid.

Note: These records are created as an exception condition.
