REPLYSECURITYLEVEL 1Usage notes
Suppressing sensitive information such as IP addresses from client replies increases the security of your site; however, such information can be useful for debugging. An alternative to getting this information from server replies is to activate the server trace to capture this information. See z/OS Communications Server: IP Diagnosis Guide for information about diagnosing problems with server traces.
