Before you begin, determine what z/OS® systems need to participate in your multilevel secure network. For each z/OS system, determine what release level it will be running, what sysplex it is a member of, which other multilevel secure systems it needs to communicate with, and what security labels will be used.
The following subtopics include some references to additional information; more information is in z/OS Communications Server: IP Configuration Reference and z/OS Security Server RACF Security Administrator's Guide.
