You can configure local IP security policy using only a unique and separate stack-specific IP security configuration file for each stack on the system. In this instance, a common IP security configuration file is not necessary.
Perform the following steps to configure local IP security policy using only a stack-specific IP security configuration file.
Each stack on the z/OS® system will adhere to the policy that is specified by its unique policy file. Stack TCPCS uses the policy that is configured in /etc/TCPCS.ipsecpol, and stack TCPCS2 uses the policy that is configured in /etc/TCPCS2.ipsecpol.
