Connection parameters are typically defined once at the port level. Sometimes it is useful to have different connection parameters depending on the Client Identifier. The PARMSGROUP and PARMSMAP statements allow connection parameters to be mapped at the Client Identifier level. This level of granularity applies to almost all parameters. See z/OS Communications Server: IP Configuration Reference for a list of Telnet parameters allowed in the PARMSGROUP block.
Assume the PAYROLL department is assigned the highest level of security and connections are being monitored with summary debug messages, general users are assigned negotiable security, and inventory employees are experiencing intermittent problems with Telnet connections that require detailed debug messages for resolution. The following statements assign the security and debug levels to the areas needed and do not affect other areas. See Transport Layer Security for security information and Telnet diagnostic tools for debug information.
