CI1 or CO1 trace entries

This trace record provides information about the inbound and outbound requests sent to session services to begin or end a same-network or cross-network LU-LU session.

The CI1 and CO1 traces have two formats:
  • Format 0 is used for same-network sessions or when VTAM® does not know whether the request is for a cross-network session. This format contains parts 1, 2, and 3 of the CIn or COn record.
  • Format 1 is used for cross-network sessions. This format contains parts 1, 2, 3, and 4 of the CIn or COn record.
