Use the optional PARMSMAP mapping statement to map a PARMSGROUP to a Client Identifier.
>>-PARMSMAP--parmsgroup_name--+-Client_Identifier-----------+-->< '-clid_type,Client_Identifier-'
A single Client Identifier can have several PARMSGROUPS mapped to it. See the PARMSGROUP assignment information in the Telnet topic in z/OS Communications Server: IP Configuration Guide for details.
