Mapping Objects to Client Identifiers

Telnet provides flexibility for mapping Objects to clients based on Client Identifiers. This topic provides definitions, rules, and examples of many mapping methods. Examples start with simple concepts, then progress to more complicated concepts showing interaction between mapping statements. All mapping statements are specified in the BEGINVTAM block. See z/OS Communications Server: IP Configuration Reference for statement rules not discussed here.

The general relationship of mapping statements is:

MAP OBJECTS to clients based on CLIENT IDENTIFIER

Telnet tries to assign all 11 Objects to a client based on the mapping statements when the connection is accepted. The search for Objects continues until all Objects are found or until all mapping statements are checked.
